No, that is not 'my god,' it is your straw man. If one kills a rabid dog or a man-eating tiger, this is not a matter of punishment, but rather of protecting the innocent. You reason as if there were only two alternatives, a vengeful God, or a passive one who never acts to end evil. The vengeful god is the god of Old Testament pagans; capricious, envious, and wrathful. The vengeful god is one kind of reductionism. Another type of reductionism is the God never kills or destroys.
We construct those reductionist deities to alleviate the need for the intellectual and emotional effort required to wrestle with the God portrayed in the Bible. Jesus withered the fig tree--a destructive act, surely. It is, as scripture says, a 'strange act' for God to destroy, but scripture makes it clear in multiple places that he does just that. The Revelation 19 passage I mentioned earlier is just one, but a very pointed, example. The mass of verbiage required to deny these examples is an indication of how weak that position is.
Because of the many examples of God commanding or approving of violence--see Samuel's dispatch of Agag, for example--the God never kills argument requires multiple different explanations (or did he merely "hide his face" when Samuel hacked Agag to death? And why didn't Samuel get the memo?). This violates Occam's Razor, and renders the position inconsistent and incoherent.
You seem sensitive to any perceives slight, yet quite willing to define another's position falsely in the most pejorative terms. Black-and-white, false dichotomies are not constructive to the discussion, and not expansive to the intellect.
