it's more custom than religion.

Like if a person u grows up in a village where chopping heads off their enemies or eating their internal organs or drinking their blood is a tradition passed on from generation after generation...

and that tradition still continues to this day...

That's what u get when people are afraid to break tradition and think on their own and live life the way they want.

Islam is so strict that islamic people are afraid to break tradition.

In Christianity, u can decide to become an athiest and nobody's gonna stone u to death.
