No, this isn't some little flaw. You baited him, and he got mad.
What if I repetitively poked you with something painful and annoying while you were blindfolded and tied to a chair, and I go and bitch about it when you complain about being in pain? Yes, Master took it too far, but baiting isn't an acceptable means for dramaing someone for raging. And don't gimme that stuff about "But that's different" or "That's not the same". Master's reason for raging is reasonable, albeit the volume was too much.
