You just captured your worst enemy...

Just a moderately sharp knife and as much time as I want will do.

Well, I would make some comfortable living quarters and see to it he has proper and extravagant amenities. If he needs anything, he can just ask me or the supervisor I left in charge of keeping an eye on him. The request can be denied if it is unreasonable. He will have the authority to turn away or accept visitors. The supervisor will have veto authority. I will have higher veto authority than the supervisor.

At some point in the future, I may choose to let him free, or simply transfer the ownership of his living facilities to him if he has no better arrangements.
There are no other stipulations.

You see, Escapist. Unlike my enemy, I am a gentleman.

Step one: Tie them to a chair.
Step two: Punch them to death.

It'd be so much more satisfying and personal to use my own two hands..

 

[stormeris]

I'd tie them up to a chair.
And force them to watch Baby Geniuses. ALL OF THEM

MAUAHAHAHAHAHAHAHAHAHA

Then maybe Batman and Robin, because i'm a sick person. SICK I TELL YOU
