This isn’t a Reddit problem, it’s a human problem. The more people who join, the more trolls, edge lords, and just plain assholes will show their ugly heads. Instead of lamenting the “Reddit like” nature and jumping ship, I’d say just work on tailoring your experience. Stop browsing All, subscribe to the communities you enjoy, and block or ignore the instances and people you don’t want to see. We have the ability to tailor this experience to our liking, it just takes a bit of effort. And above all, just keep being positive and encouraging to others and that will spread around.
