I'm looking for a word or phrase that describes somebody who convinces other people to do wrong.
"Coercion" comes close, but I'm looking for something that doesn't imply a threat.
"Ducking" is a prison-slang term for when a prisoner gets the guards to do things for them. I would be happy with this except that it's very specific.
"Brainwashing" is almost halfway close, but not really.
Real-life examples are rather grim, such as a person who convinces another to be a suicide-bomber, or perhaps racism in general.
I'm a racist because I was _____ed
Watch out for Henry, he's a ______
I would be particularly happy with an answer if the word/phrase was meant to be used as an insult.
