Randy was pretty homophobic, he clearly states in his tapes about a time some dude talked to him on twitter or something about being gay, and how he was grossed out by it. Honestly, a lot of Randys problem could have been intrinsic homophobia along with GD.I think randy would hated chris hated to the point of killing him
and it would be very likely that if randy was still alive and committed the massacre later he would of shot chris first by driving down to Virginia killing him and going back up to penn and the rest as they say is history
but that is my take
IDK if he would've went out of his way to kill Chris, but he would have certainly called him a faggot and would have left it there.
