I will make you shorter by the head.

There is an Italian proverb which saith, From my enemy let me defend myself; but from a pretensed friend Lord deliver me

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

Friendship Never explain / your friends do not need it, and your enemies will not believe it anyway. A real friend never gets in your way, unless you happen to be on the way down. A friend is someone you can do nothing with and enjoy it. However much we guard ourselves against it, we tend to shape ourselves in the image others have of us. It is not so much the example of others we imitate, as the reflection of ourselves in their eyes and the echo of ourselves in their words.

Monarchs ought to put to death the authors and instigators of war, as their sworn enemies and as dangers to their states.

...nothing cements a friendship like hating the same person.
