He said his dad liked to drink after a long day. That doesn't mean a drunk, that just means he had a bad day and wanted to calm down.

Also, when you're an assassin, you tend to be smart enough not to teach your kid everything you know (as implied by Cinder's "He taught you well" comment) and then be a collossal douche to him. The kid you are being a dick to lives in your house, has access to all manner of weapons that you are teaching him to use, and is being trained as an assassin. It kind of goes against common sense to treat him like crap.

I'm not saying they had the best relationship, but I doubt they had a terrible one that resulted in Mercury being the one to kill his father. I think it is more likely that either and accident happene,d or someone attacked Marcus and the Black family teamed up against them. In the aftermath, the house was burnt down and Marcus died. Cinder hired Mercury because he showed he had skill and the ability to deal with enemies, as well as being able to survive attacks.

When Cinder asked him "Are you anything like your father?" she was actually saying "I have a job which I was going to ask your father to do and am now asking you instead. It pays. Do you want it?"
