I don't mind the fold. You really don't know what tilt guy has, although you can assume it's a wider range of hands than he usually would raise like that. AK vs. two random hands is not a big edge, especially if one of them is a pocket pair. In this situation I'd prefer to have at least a pocket pair to call with - jacks or better.

vs. their actual holdings you were in a good position (50% to win) but vs. say pocket nines and KQo, you're <40% to win. Which is decent against two players, but still not really the kind of odds you're looking for when going all in.
