The wicked have no friends.

He will never have true friends who is afraid of making enemies.

Friendship is impossible with a liar.

He that is neither one thing nor the other has no friends.

De quien es pobre, nadie quiere ser amigo.

A foe to God was never true friend to man

Evil cannot be conquered by wishing.

...good can never catch up with evil, because with the gap between good and evil there is no hope whatsoever.

A friend is nothing but a known enemy.

There is no inspiration in evil and no power except for its own destruction.

He makes no friends who never made a foe.

There can be no justification for choosing any part of that which one knows to be evil.

He who is bent on doing evil can never want occasion.

Evil exists, and the good, sad to say, can never catch up with it.
