Most people are incarcerated for the reasons you list. [0] That doesn't necessarily make them a scumbag or a bad person in my mind, without knowing more about the situation. There are plenty of examples where it's not so clear cut, here are a few:

Supposedly over 90% of convictions are from plea bargains. We'll never know how many of those people were actually innocent. CeCe McDonald may or may not be one example. [1]

Anthony Gammons, Jr. may have acted in self defense for him and his child, but he wasn't legally allowed to own a firearm so he was convicted of murder. [2]

Teenager gets 10 years for consensual sex. [3]

Kalief Browder in jail for three years without a trial. [4]

Alexander Torres wrongfully convicted for murder for 20 years. [5]

When I was in jail, the few people I talked to, were in there for cannabis possession (as was I), driving without a license, and missing a jury summons. None of that necessarily makes them bad people in my mind. Maybe they are, but it would be for other reasons I'm not aware of.
