Slide side-track but the older I get the more I realize that (at least for me) having to deal with other people is a path to "salvation", not "hell."
When I was younger, I found certain types of people and interactions difficult and painful. I was very quick to judge people who caused me this "pain" as bad people, and so I always interpreted the quote that "hell is other people" as a reference to that.
But lately I've come to realize that these negative reactions have much more to do with me than with the people. I react(ed) strongly to certain people and things because of my own emotional baggage, etc. and I've come to value these interactions as pointers to where I need to work on myself.
So I find that having to deal with people actually forces you (or at least, forces me) to confront your own issues, it's a form of therapy although obviously painful in the moment. The alternative is to avoid all these triggers. For example, someone in my family chose to spend much more time with plants than with people in order to avoid all these painful triggers, but as a consequence I see her "spiraling" more and more into her own emotional dark places rather than being forced to stay above water by social interactions - by being forced to confront and work through the issues.
Maybe this is not universal, maybe it only applies to me, but I see that the more work I do on myself, the less I agree with "hell is other people" - which means there was never really a big problem with them, only with me.
