I don’t detest very many people, at all. Almost certainly, I would talk to my lawyer to devise how best tactically to securely give the evidence to the police and possibly offer to further entrap the person I despise. The only circumstances I can dream up where I might accept the money, would tend to involve some additional danger where I felt I had little choice, or tactical situations where I thought I could take the horrible person’s money and see him destroyed and later exonerate the innocent person. For example, if he were a criminal who also stood to threaten people I care about if I don’t comply, I might conceivably devise a plan involving taking the money and using it to destroy him and get the safety and exonerate the innocent person.
