Doom in the comics is more like movie Thanos than comic Thanos. Comic Thanos is legitimately mad and killed half the universe just to impress Mistress Death (she was not impressed).
He's basically Stark, Strange and Black Panther rolled into one, with the arrogance of Strange and Stark dialed to eleven.
He's completely capable of doing very evil shit to reach his goals but also has moral principles. He has tried to kill the Fantastic Four countless times and is still the godfather of the daughter of Reed and Sue. Her first word was "Doom".
Also social media sequestering people in cozy filter bubbles that distort reality.
Social media, or more precisely, algorithms designed to create ever growing engagement by feeding into confirmation bias and only showing you stuff you like, have destroyed the ability of critical thinking in a majority of people.
This doesn't only apply to the right spectrum either, as evidenced by all the "hopium" articles here and on r/politics that were trying to construct a blue win or even a blue wave when all polls pointed to a Trump advantage. I had fallen into that trap myself. And everybody was also smugly making fun of the articles in r/conservative predicting the same thing for Trump. Well, turns out they were right.
