He might get angry, but that just makes him kill you harder.
Never, ever piss Alucard off. Not that it's easy to do.
He does admire humans though. That's why he wants to be killed by a worthy one. You'd think he'd be pissed about Schrodinger but he seemed pretty happy about it.
I mean in the end, the Major gets credit for killing Alucard. Schrodinger was just a tool. Major fucking won. Apparently he was just the right kind of guy to kill Alucard.
