I disagree. I don't think accepting reality would force Jazz to off himself. Men have survived having their sexual organs being injured or removed, wether it's cause of cancer, running over an IED in Iraq, or an accident. These are all awful experiences to go through, but they're survivable. Men with mangled penises and messed-up endocrine systems can still have good lives.
People have survived cult upbringings. People have survived being victims of wars and horrible crimes.
There's a theory of personality development called "positive disintegration". It postulates that the psychological tension that comes from going through bad experiences is necessary for growth. Jazz has the potential to realize what was done to him, accept his reality, and use that as an opportunity for growth, not despair. I don't think his suicide is inevitable, and I hope he goes on to live a productive life.
