Is there a villain you just feel BAD for?
Obviously the villains are the bad guys. But every once in a while... don't you just feel a teeny bit bad for them? We know they're going to lose, and that it's probably going to be painful... so even though they've done terrible things, don't you feel sorry for them?
Maybe it was just Tom Hiddleston's performance, but I feel a little bad for Loki sometimes.
He's terrible, and vindictive, and selfish. But he's also frustrated and feeling neglected and under-appreciated. I definitely don't have plans to take over the world! But I can relate to that at least a little. Can't everyone?
