A simple question

[rusty pistol]

Playing live 3/6 with a kill. This is a kill hand. The player with the kill has just moved to the game about 30 minutes ago from a game that broke. He has shown some agression and will bet with any part of the board. In the previous hand he raised and then capped the turn on a gut shot draw because, in his words, he wanted a kill pot if he won the hand. Obviously he won. Anyway on to the question.

It's folded to you in the BB with only the kill left to act. You look down and find 3c 3s. Who calls? Who folds? Who raises? and why? I'm just looking for other posters opinions on how they would handle this pre-flop based upon what little info they have available.
