Do you support capital punishment?

[Gaijin]

... Some people just deserve to die, There was a dude (I can't remember where) that locked up his daughter for 16 years or so and had about 10+ kids to her, she was a sex slave!

I think you are talking about that Austrian dude, such people deserve to die.
As for murder, crap happens, some do it out of anger, some do it because of a mistake, some do it because it's their job.

But every action done against a child is to be punished with death so those people can't even think about that stuff anymore.
Without thinking.
