Betrayal is an experience that anyone is susceptible to. In video games, and many other stories, betrayals that are the focal point are often ones the hero is dealing with. That said, villains are just as likelyif not more soto deal with betrayal. If certain villains have lowered standards of decency, they are more likely to invoke disgust from potential allies, or maybe even be more inviting towards those with means and motives to betray them.
