Punishment always follows excess.

Pardon the offence and you will encourage more.

Every light has it's shadow.

Shame follows pride.

If you deceive others, you also deceive yourself.

Man who pats himself on risks broken arm.

Keep company with wolves and you'll learn to howl.

If you dig a pit you might fall into it.

Fear is the parent of cruelty.

Revenge is it's own executioner.
