@ starconstant. You got the wrong quotes there. FYI. But it still begs the question of the need to justify the act. You don't justify a good act, no one does. We justify something when we think it is wrong. They can think it necessary or feel they have a reason but if they feel the need to justify it they feel guilt towards it, thus making the action wrong/evil whatever. to justify something is to prove that they should be excused for that action, absolved. I'm sure all of would agree that killing is wrong, I hope. If I kill someone it is wrong, if I justify it by saying that I did it because he was breaking in my house to kill my family then it is excused as being just. the act is still wrong but deemed necessary.
