Not sure Id characterise his first relationship with Angie as evidence of 'responsibility'. They had about as open a marriage imaginable. It was probably all over by '75 at the latest and despite her erratic behaviour I think its fair to say that his treatment for her wasn't the best - he went for long periods without even speaking to her, using his staff to screen her and going so far as to stay in hotels when they were both in London at the same time.
His most callous moment I think was his treatment of Ronson and the Spiders, dumping them Neil Young fashion right at the height of the bands popularity. Ronson was extremely bitter about it, though they did reconcile a few years later. Ronson went on to play with Dylan, who took him on tour and then refused to let him play.
Also the near constant coke induced paranoia that led him to take Laurent Thibault, off the production credits for Low.
All in all though, considering his fame and wealth, the amount of drugs he took and the length of his career, the list of grievances seems pretty short.
