Did House care about Kutner??

So I just completed episode 20 of season 5, where we find Kutner killed himself, and when House goes to investigate, Wilson says he’s trying to find it not because he cared about Kutner, but rather another mystery, and at other points that if it is a murder you couldn’t blame yourself, or at the end that House was afraid of losing his gift…

So did he care about Kutner or what Wilson said is right(can be both) what do you all think??
