Things that most people have which stop people from doing things that either:
1) are mean or unfair to other people or
2) have been outlawed by a higher power, such as the police or God, usually for the protection of others' health or rights.
Morals do not have a physical form, although some "codes of conduct" attempt to represent them.
Guy #1: Let's go steal some wallets!
Guy #2: But that's not fair to the people who own the wallets! You have such bad morals!
Things that make weak people bend over and take it in the rear from society.
Guy 1: Let's go steal shit.
Guy 2: Nooo, that's baaaad. We shouldn't. Think of the morals!!!
Guy 1 shoots Guy 2.
