Each man was his own executioner and his own victim.

Every man has his personal devil waiting for him somewhere.

Each of us is the enemy [...] to the other and to himself. That's what I mean: I'm the enemy within myself. Unless I master that enemy, I always lose.

Only man can be an enemy for man; only he can rob him of the meaning of his acts and his life because it also belongs only to him alone to confirm it in its existence, to recognize it in actual fact as a freedom

Like every man I am my own worst enemy, but unlike most men I know too that I am my own saviour.

Every man has inside himself a parasitic being who is acting not at all to his advantage.

Each man kills the thing he loves.

The most dangerous enemy is the one within.

Each man kills the thing he loves

Често човек е най-злият враг на самия себе си

The true enemy of man is generalization.

Every man must bear his own burden.

A man friends are more capable of working him harm than strangers; and his greatest
danger lies in his own habits.

The man who kills a man kills a man.
The man who kills himself kills all men.
As far as he is concerned, he wipes out the world.
