Primates have already been domesticated, at least to some extent. Remember the episode of the Simpsons where Homer gets a helper monkey? Some old/disabled people do actually have helper monkees. I think the main reason why people dont have them as pets is because it takes a long time to train and domesticate them. As others have said, primates are naturally violaent and it takes a lot of effort to train that out of them.
