If sean had come on and posted that he 4b to 125 and villain folded, I guarantee everybody would have said "make it smaller". Stop being results-based dave.
I guarantee you I wouldn't have, my very first reaction on reading the description of the villain was that I would make a HUGE 4bet here.
There is nothing to induce but a call from mr. tilt or a 5b from the 3better IF he has a good hand (which we'd get regardless of our sizing, and I don't think it makes much difference in this game) If Mr. Tilt is overcalling a 3bet and is over-overcalling a 4bet, I really cant see that an extra 30quid is going to discourage him, but he's almost certainly fit-or-folding the flop (so the more money we get in pre-flop the weaker he commits himself post-flop and the more money we make when he chk-folds - I realise in his current mental state he prolly won't need to over-qualify to stack of post flop, but he's going to have a weak enough range that misses the flop and chk/folds a decent %)
Obviously none of this is theoretically optimal
