raising is a mistake if he is going to fold.

I agree in general because he may lose his stack with top pair. However, if he has a pocket pair and will only continue if he hits a set, then raising is correct even if he will fold. If you call, 7.5/8.5 times you win 480 chips. The other 1/8.5 times, you lose your stack or close to it. 7.5/8.5 *480 - 1.5/8.5 * 5000 = -460 chips. i.e. You lose 460 chips by just calling if he has a pocket pair. I approximated some numbers but the conclusion is still valid.

Well put, Steve. This is in addition to the fact that raising is also the correct way to ensure we get Villain's stack when he hits with a number of his other possible holdings.
