How can you know if what your seeing or hearing is right or wrong?

All you have to do is know the Seven Deadly Sins.

The Seven Deadly Sins are:

1.) Lust, the opposite of lust is chastity.
2.) Gluttony, the opposite of gluttony is temperance.
3.) Greed, the opposite of greed is charity.
4.) Sloth, the opposite of sloth is diligence.
5.) Wrath, the opposite of wrath is patience.
6.) Envy, the opposite of envy is kindness.
7.) Pride, the opposite of pride is humility.

If you can do the opposite of the seven deadly sins then you will find out that bad things will rarely happen to you.
