I'm saying that killing mass murderer won't change him because he killed before and killed not mass murderers but innocent people. If killing didn't change him for worse then killing again someone that actually deserves wouldn't either (even more so).
Actually, killing innocent people has affected Roy in negative ways. He will always be haunted by those deaths (Roy wouldn't be the moral human he is if he did not think about it). He will always feel guilt. He has lost the freedom to choose his fate (he wants the planned democratic government to try him for war crimes, with the possibility of execution).
Either you're using straw-man argument and are trolling or you really can't read with comprehension. Yes, the deaths he had caused affected him but
he didn't become worse person, on the contrary. Because his conscience haunts him and because he deeply regrets it I doubt he will make the same mistake again, i.e. he became better person.
Below you will find that I've commented on every sentence in your quote:
QUOTE
A person with his morality and immoral record must often worry about the day he might lose that morality. [Huh? Are you omniscient? Do you know what Roy feels? Besides, every person has to watch out not to lose his principles.] Just because 'the worse' hasn't happened before doesn't mean it won't happen in the future. [lol, again general statement that has nothing to do with our quarrel, I can write as well "Just because 'the worse' hasn't happened before doesn't mean it WILL happen in the future", but it proves nothing, that's just spam]. Thus, Roy strives to make sure that loss never happens. If he has to kill, it must be for the noblest of reasons. [WHY? Because YOU think that. Again it proves nothing, you're going around in circles. You're basing all of this on the premise that after Mustang kills Envy he will destroy himself, which is yet to be proved.] So when he killed Lust, his fury was based on 'Don't you dare touch Riza and Al!' (And Bradley saw this act was done to protect Riza). [But it was done also because of his anger towards her. In Envy's case we have different proportions, more anger, less concern about his friends but the situation is different too. Lust almost owned Mustang, Havoc, Riza and Al, Envy couldn't manage to own anyone and now she has 4 opponents, so why Mustang should be concerned about their safety anyway? I'm guessing the difference between Riza and Mustang killing Envy is very thin. Riza wants to kill Envy, firstly to protect Mustang, secondly to avenge deaths of people Envy killed, thirdly to protect herself. Mustang wants to kill Envy firstly to avenge Hughes' death, secondly to protect others, thirdly to avenge deaths of people Envy killed.]

During the revolt, Roy used his alchemy to defeat but not kill the opposing soldiers.
IE he became better person. You're shooting your own feet.
QUOTE
But right now Roy is not thinking about the other people or anything near his principles. He is only feeling his own personal pain and anger over the loss of Maes Hughes (who, I definitely believe, would never condone this action), and throws all that rage on the person possible. It's his own selfish vendetta, and selfishness is not noble. Killing done under such negative emotions spell B-A-D for the killer; Riza, Scar, and Edward see that.
Ed knows about this only as an observer, i.e. almost nothing. He knows nothing about Roy nor about killing. Scar knows about revenge but only blind revenge and nothing about Roy. Only because it affected him like that doesn't mean that it would affect Roy (and I'm not sure if he knows what Roy did in Ishvar. Mustang was the one that killed last Ishvaran and an old man at that). I've written before why he can't understand him. Riza knows a lot about Roy but not much about revenge.
You can't know what Roy is thinking about or what he feels. Your interpretation is as good as mine. Just because he shouted at Riza (oh, no! He shouted at some female!) doesn't mean that he wants to kill Envy
only for his selfish reason. In that situation that's exactly what he can do. Why should he concede when he has most reasons to kill him? Because someone tells him to?
As for Hughes, I wouldn't be so sure about that. Why would he oppose? He's not a sissy like Ed and killing Envy would be as easy as snapping fingers so why should Mustang be bothered by this death more than he was when he killed innocent people? Hughes would want to kill Envy himself and if Mustang was killed I would bet that he would want to avenge his friend. Maybe if he saw that he stands no chance, he would give up on doing it himself but I'm sure he would kill her if she was in her shrimp form.

When Mustang killed Ishvarans he caused pain and suffering not only for the ones he killed but also their family and friends. He made people sh*t in their pants, he knew no mercy. So yes, I think that killing Envy, which will cause no pain to anyone else other than Envy, (on the contrary, it will only bring good things) is totally different.
Yes it's different this time: Roy, the idealist who had been
forced to kill for orders & protection,
wants to kill out of selfish rage.
Here we go again... Man, you really should put some work into reading with comprehension. He wasn't forced, he was ordered to. To force =/= to order (I'm shocked I even have to explain it to you). He could disobey orders, simple as that. Even more so because he knew he wasn't defending his country, it was one sided battle, an overkill and a waste of everything. He made people suffer and by killing Envy he won't make anyone else suffer. Even if you're right that Mustang wants to kill Envy ONLY for his own selfish reason it's still better than to slaughter innocent people. On the one hand we would have temporarily insane person that wanted to kill mass murderer, on the other hand perfectly sane that killed defenseless people because he was told to. Just because he regrets the deaths of people he killed, it doesn't make his crime any lesser. And it looks to me that the reason why Mustang didn't disobey orders was selfish.
If he did, he could have ruined his career. QUOTE
But I suppose you'll ignore my explanations. I'm probably describing life to an unborn child.
The problem is you've been ignoring my explanations all along. And your explanation are all based on the premise that: "killing Envy will change Mustang in a bad way" even though I've proved that it's implausible.
You can further naively believe that 30 years old man, very experienced at that, can change just like that. Whatever.
