Truthfully, while i thought he was a great villain, i think Bester was even better. Walter Koenig played him perfectly. But, the main thing that made him better was his complexity. He believed he was doing the right thing even when hunting down his fellow telepaths, and on some occasions, he was right, and rogue telepaths were a threat. So, sometimes Bester was in the wrong, and sometimes he was right, which in my opinion made him a better villain than one who is always evil.

He didn't quit acting just because the movie bombed. Him and the director had such epic fights on the set of the movie, that BOTH of them quit Hollywood afterwards.
