I like how your post focuses towards social ethics and humanity. Yes Cruelty and Violence always existed from past-present-and will in future too.

I have been cruel too knowingly or unknowingly to someone... It is very difficult to know the reason of cruelty, may be it rooted deep down from fear, ignorance, greed or whatever who knows.

But you are right the cycle of violence repeat itself. It takes a big heart to subdue the act of violence and cruelty.. or something.

Ugh.. I blabbered too much now XD
Great Post Bro @drekkelly
