Because stealing is mean!
Probably because it is forbidden in the commandments so people
have a sort of taboo against it.
Because it's horrible to steal. Someone robbed my friends house
and they took all her dvds and one of them was a homemade dvd with
the only memory she had of her birth mum (she's adopted). Also, her
adoptive parents are blind and their blind dog was killed. stealing
is REALLY unjust and horrid.
What if someone stole YOUR phone or something? how would YOU
feel?
