Humans.

I think we're all fucked up in some sort of way.

Humans are disgusting creatures. 

We think of things that are beyond belief. 

It doesn't matter at what age, how mature, how developed. 

Assault, homicide and rape are human actions.

They were all thought up by humans. 

They had the choice to think of it and make the actions.

Assault- Physically attacking.

Homicide- Unlawful killing of another; murder.

Rape- Unlawful act of sexual intercourse forced upon another.
