At the end of it all, people won't remember your work - but they damn sure will remember how you made them feel. They'll remember how you treated other people. Ultimately, that will be the judge of your worth in the eyes of whatever community you participate in and society broadly.
Few people do work that transcends awful character. Very very few people. Steve Jobs is an example, but let's be honest neither you nor I will have the same level of impact to excuse ourselves after treating others terribly.
With that being said, I admire your effort to mend things and the bit of self-reflection in your response.
Do you think Steve Jobs made contributions that outweighed him being a jerk? I don't think that ever happens, in that I don't think you ever forget someone being a jerk, but then I don't think we aren't capable of appreciating the good and the bad at the same time. There must be studies around this. Maybe someone is aware of some.
