Yes, a moral dilemma thread.
So, one day your best friend calls you up and tells you he/she needs to talk to you in private - they sound worried.
You get to your friend, and they tell you they just murdered someone. The specifics are not necessary - but you know that they killed someone in cold blood (wasn't involuntary) because they absolutely hated this person, and now they're looking to you for consul.
Assuming you believe them, and they are telling the truth, how would you react, and what would you do?
