That's like saying if a serial killer, or Hitler, didn't kill those people, we wouldn't be where we today, so we should respect or honor them. Give me a break. Stop making excuses for these creatures who mindlessly are trying to save themselves, and themselves only. If I was a dragon, it would be different. But they prey upon our innocent families for their own reasons. It's my prerogative to stop these beasts. Sure, I feel bad for their destiny, but I feel much worse for what they want to do to ours, at least the ones who attack on sight.

Ummm sorry to rain on your guys parade but it's a video game, so no I Don't feel sorry killing anything in video games. Accept for children which we can't kill.

"It's just a game" argument is invalid and dosn't count as a solid argument.
