It is willful depravity on the part of those who embrace pacifism in the pursuit of the feeling of righteousness. They mentally rewrite reality and blank out any verifiable fact that contradicts illusion of moral superiority. They simply do not care about the actual human lives destroyed by real tyrants and conquerors as long as they can feel good about themselves. They are willing servants and accessories to the Enemies of Human Kind.
Pacifism is evil pretending to be good at the expense of the innocent and helpless. I would argue that pacifists hold a lower place in the objective moral order than child molesters.
