Moral and emotional dilemma

Does he deserve a second chance or am I crazy for thinking this way? I been in a relationship with my boyfriend for 8 months, He is a loving, caring and kind person but as the relationship progress, I noticed how moody he gets and his bad temper. I discussed the issue with him and it was ok for a month or so, only to get worse as time gone by. The latest incident really concerned me because he shouted at me in a shop, and told me we were finished and I can walk home, although I was in my friend car and had no money to get back to my place. He came down after a short while. As we got in the car, he started crying, apologise profusely and said he was disgusted with his behaviour, I told him to seek help for his anger as I will not put up with it much longer. For the next two weeks, he was, caring, kind and affectionate, the type of person he is normally and the reason I was attracted to him in the first place. I also like to add he has been hurt badly in relationships in the past and he is hypersensitive I also notice he wasn’t sleeping properly, when I asking why, he said he had to tell me something about his past and that was part of the reason why he kept losing his temper and had not told me yet because of his fear about my reaction to his confession. I persuade him to tell me what was bothering him and eventually he told me, When he was Twenty one (twenty years ago) he was convicted of rape and spent a year in prison, he said what he did was wrong and bad and something that has haunted him ever since. He also told me he got raped in prison, at this point, he got really upset. When he came out of prison, he got married and had a child but the marriage did not work and because of his criminal record he could not bring up his child. (His ex wife gave the child up for adoption). He stayed away from relationships for a while after that and then he had a relationship with someone for three years and half years but apparently it ended because she was having an affair.( I knew he had been married and had a child and also about his other relationship, he told me this at the very beginning of our relationship). I’m in extreme shock as what he confessed to ,and deeply hurt, before he told me he said it was eating him up inside and he knows how much I value honestly in a relationship, so he did not feel we can continue our relationship , unless he told me what happened. I love him very much but I feel I do not know who this person is anymore, part of me feels he deserves a second chance at life and I do not want to judge him but my views about rape are black and white, I was sexually molested a s a child, I’m over it and had counselling . I would also like to add that he has not behaved inappropriately with me or been pushy in anyway, otherwise he would have not lasted a week, let alone 8 months. He often jokes he thinks he has a borderline personality disorder. Am I letting my feelings cloud my judgement? Should I just end the relationship, He said he will go to counselling for his anger issues. I have not been able to discuss this issue with my friends as I he is extremely paranoid my friends are going to judge him for his past actions, Any advised will be gratefully appreciated. Thank you

8 months is too short a time to judge him having known his past records.Life with this person is surely not easy thats why he had 3 women in his life who left him abruptly for reasons he knows best. The 2 options in front of you are 1. Leave him and move on. Easier path. 2. Continue with him for sometime more without any serious commitment. Don't know how far you can trust him with all his temper tantrum and if that was the reason in the first place to attempt rape. Which is the real him? The one who is caring, kind and affectionate or the one who abuses? I think you need to do some research here to verify facts on him. Speak to people who knew him for long time, speak to the person who is taking up his counseling etc. Having said that, assuming he has been 100% honest, Life with this person will not be easy. At every stage there will be stumbling blocks....some because of his past....some because of his temper issues. Decide whats best for you.
