Most people don't like people who do bad things, like stealing and mistreating others. However in fiction, a lot of popular characters are villains, like Loki or Darth Vader. Meanwhile, people who are nowhere near as bad are sometimes hated by audiences, like Felicity Smoak in Arrow. Now in real life, this is a different story, but it is interesting to think and talk about. For example, the recent episode of Stargirl had Starman go on the attack against Sportsmaster and Tigress, two former members of the Injustice Society who killed his friends and participated in a scheme to brainwash 75% of all the adults in America, killing the rest. They have yet to really atone for all of this. Yet, a lot of viewers were unhappy with Sylvester, mostly because he destroyed a grocery store in the process of the attack. Meanwhile, Sportsmaster and Tigress are two of the popular characters on the show.
