Am I meant to stay away from ugly, hateful, spiteful, vengeful thoughts if I am a Christian?

Sometimes i imagine taking revenge on people who has done bad things to me and i can't stop thinking about to seeing them hurt.

Although i don't act on these ideas, i am still worried that they might contradict the message of Jesus. Thank you.
