Well, to say you'll never find a vegan murderer is actually a bit off. A vegan, and animal rights activist in my country, Volkert van der Graaf, is actually incredibly hated for having murdered an upcoming politician. Van der Graaf was a radical leftist, and without concern for the enormous backlash and divide his actions might create in the Dutch nation and its politics, he went ahead and murdered Pim Fortuyn.
Now I might not have agreed with everything Fortuyn (the politician) said or thought, but to murder a man and therefore stifle the mouthpiece of an idea is absolutely disgusting.
Of course, I understand your point. This was just one rotten apple.
