I often kill bugs when I see them. I don't like them. Most people are like this. Yet we are not serial killers. Bugs suck. Only some weirdos like entomologists and other related dorks (I am using words like "weirdos" and "dorks" lovingly, as I am a different flavor of said descriptions lol) love them! It's perfectly natural to hate all bugs imo. I wouldn't be surprised if we are genetically predisposed to dislike them because of how they spread disease.
