Well, it's already been hinted that the MC has some unresolved rage issues. Earlier we've also seen that even half-conscious MC can take on Ryker one on one. And Ryker seems to be the type of asshole who can't help but push MC's berzerk button in some sort of Alpha male dominance play. Since MC's button is clearly going after his loved ones (and his stable of loved ones is growing every update) it seems a confrontation is almost inevitable.
How it will play out is up to Braindrop of course, but personally I wouldn't mind seeing a pint of Ryker's blood spilled. And Rachael will play the part of The Wolf in Pulp Fiction in dealing with the aftermath.

I dunno...... The inner thought dialogue when we see him on day 6 does have the MC doing everything in his power to restrain himself from putting him through a wall so I'm sure a capacity for violence is there to a degree. Also we already know a fixer and while I agree having him killed doesn't seem like rachel's style I'm sure she could ruin him to the point he wished he was dead easily enough.
Or that. Rachael has show herself to be a very cunning bussinesswoman who is not afraid to take on Dean Charles, so she would probably eat his whiney virgin nephew for breakfast and still have room left over for an MC sperm deposit.
