If he wanted his product to end, it ends with the death of Jesse....who he didn't he want to kill, for obvious reasons. Hell he didn't even talk about his part in Grey Matter to Gretchen and Elliot(which I think most thought he would), which is why I found it odd he wanted to kill her so badly for distributing his product. Eh, don't matter too much. Just don't think she had done anything woefully bad to him, that he knew of, like the others he went after. Shes still deserved her death, so barely matters, just could of met Skylar before it maybe.
