That's true. lol. But for me it was getting a tad too gratuitous, kind of like a torture porn movie. I mean he had no reason to throw Poseidon's serving girl (or daughter?) into those gears. A minotaur corpse would have had the same result. (Hell, it likely would have worked better because I imagine minotaurs and monsters in general have thicker bones and denser muscle mass than most humans do)
Maybe Kratos simply wanted to hurt Poseidon on an emotional level but it's hypocritical Kratos is just as petty as the gods themselves while fighting them.
I'm sure Marianne would argue it's deliberate irony and adds to the tragedy of Kratos as a character yet you cannot deny many of these scenes of wanton violence tend to appeal to the tween dude/bro demographic. Sadly, most 15 year olds aren't going to grasp Marianne's deeper messages. (Unless they replay the games at 20 something and finally understand.)
As far as these kinds of characters go, I rather throw my lot in with Dante or Ryu Hayabusa. At least they can "reason" and not everything they do is because of blind idiotic rage. Kratos is "awesome" as a character in design but he would be a terrible friend and a terrible rescuer!
