Two way to look at it . He was smart or most of his vitims were dumb/ gullible/ too trusting
Lot of his vitims would be alive to day if they had just walked away
What made Bundy able to kill so many women, more so than any evil wit he may have possessed, was simply how unthreatening he looked. He looked like an accountant you would take your taxes to not a murdering maniac. I think up until Bundy people had this image of seriel killers as people who looked and acted obviously insane. And some have looked and acted that way. But most of them look and act perfectly normal when they want to. Bundy was the epitome of that.
