nearly ending it HELP

I've been dating a guy for around 2 years now. He is funny and really smart, and he has helped me find ways and the strength to cope with constant illness. If that were all it would be great but there are some major problems. His family is at the heart of my issues with him. It centres around his father's (shall call the father H) behaviour. H likes to belittle, irritate and frustrate people because he finds it funny. He intentionally baits people (example: he found out i worked at a vet and so kept going on about shooting animals that strayed onto his farm and laughing at the owners when they came round looking for them). He had warped ideas on how to raise his sons so they would be 'tough'. The sons survived amazingly but the H's treatment of them could easily be classified as serious abuse and neglect. the mother (G) was an only child of a prisoner of war veteran who had PTSD. I don't think she understands this is not normal. She looked after the daughters more and left the sons up to H to raise mostly. the resulting son that i'm dating has serious problems. when I started going out with him he confided that he had been suicidal. He has major issues with hygiene and does not keep himself clean. Same jeans for weeks, never cleans hands or brushes teeth etc. I wasn't going to put up with that so he has improved a lot but still not great. Bare in mind that he used a lack of hygiene to prevent people physically bullying him (which would have originally been because of who is father is). Literally no-one was willing to touch him to beat him up. It lead to a lot of verbal bullying though which has in term lead him to be very distrustful and unforgiving of other people. he also is really bad with sorting problems. Anything goes wrong he shuts down and does nothing. We are students so get a subsidy to pay rent while we study. Something went wrong with his application and the payments didn't go through. the result was he just left it and went without power till i forced him to call and sort it. he did and it was easy enough to do, but now payments are going through his mother because he is obviously incapable of handling it. He hasn't had a proper job either and is struggling to get one (possibly because no one wants to work with someone that can apparently stink out a room: i should note that illness mentioned above means i can't actually tell he smells, everyone else just tells me he does). I can't tell if he is lazy or terrified about getting a job. He definitely has low self confidence. I could handle all of this except for the father and the fact I worry he will be like his father. On top of being abusive H thinks it is really 'smart' to cheat people. He has this thing about it being his cultural heritage to cheat and effectively steal from people. (ie "borrowing" building material from work, using insider knowledge to by a property for cheap). the guy i'm dating thinks some of what he does is smart (sometime even i'm amazed at what he manages, amazed and horrified). I don't like it and i don't want to accept that but i feel like i'm condoning it by going out with this guy and knowing about it. I can see all the good points and bad points of everyone in his family, and i understand why they behave to way they do, so it is hard to blame them because they don't think they are harming anyone (they believe they are rebelling against the big companies that are suppressing everyone anyway). Is it possible that if i explain it and make it clear to him i can't stand it and that the world is a tough enough place that their is no need to make it worse, he will listen? Or is he just saying yes he can see why some behaviours are wrong to placate me? How different can he be from his family? It seems silly sometimes but i do not want any children I have growing up to think that sort of behaviour is right. I need some advice. Please help and I thank you for your time.

you dont have a future with him,you both come from diff worlds but continue to be his friend and try to help him,his life will improve just be a good friend nothing else
