Humanity

Last week i'd got beaten by a jealous man who is bf to the one of my friend.
I'm not blaming myself for this because i'm not even touch her.
There're things that man can talk and discuss about it.
I couldn't understand why they took the rought way.
We as a man should be ashame if we fight and kill each other to get a women.
Am i right?
Why people like this are still exist in the peacefull world?
When satan come and whisper to human, they just giving themselves for satan to take over their anger.
Why they can't think rationally?
Until when we are going up like this?
Sometimes i feel like i'm give up for humanity.
There's no way we can break 'THe Chain Of HAtred"
