Just as possible that this guy was on the same ramp up to madness that would lead to his insane outburst in another situation. It's purely speculative and doesn't amount to evidence.
Sorry, I left this part out of my initial post- I think it helps illustrate the "hate crime" aspect more: As far as I know the investigation into it being a hate crime is still underway."In this case, he’s angry about the way people around him live, but he’s chosen these specific people because they also represent a religion he’s intolerant of.” According to McDevitt, one factor that the F.B.I. considers when assessing a possible hate crime is whether “the level of violence is more than what is required to do the crime.” By that light, the fact that Hicks fired a number of shots and pressed his gun to the women’s heads seems relevant.
