What does Marcus Arlius mean when he says:nobdy can implicate me in what is degrading?

Question

"Begin each day by telling yourself: Today I shall be meeting with interference, ingratitude, insolence, dislyalty, ill-will nad selfishness-all of them due to the offender’s ignrance of what is good or evil.I have long perceived the nature of evil and its meanness, and also the nature of the culprit himself, who is my brother (not in the physical sense, but as a fellow-creature similarly endowed with reason and a share of the divine);therefore none f those things can injure me, for nobdy can implicate me in what is degrading."

Answer 1

He is aware of evil, he has seen it, he is confronted with it daily, and because of all of these things he can avoid it and won't do any of those evil things he's witnessed.

And it's Marcus Aurelius, from Meditations.

Answer 2

It means that he can't be at fault when others degrade themselves by being mean.
