Did Batman kill Solomon Grundy in Arkham City?

[The Laughing Fish]

I was playing Arkham City for the fifth time a couple of days ago. I enjoyed it as always, but there was something that kind of bothered me about the end of the Solomon Grundy fight; the one where you have to destroy those electrical generators that keep reanimating Grundy as you fight him underneath the Penguin's Iceberg Lounge. Once Batman beats Grundy, it looked like he killed Grundy by splattering his heart, But here's the thing I don't get. Grundy is supposed to be a zombie, right? If he's already lifeless, then wouldn't Batman 'killing him' off not really count as murder after all?

He could have taken a Batsaw and cut him into a million pieces and I think he would have been within his "No Killing" limits lol. I guess in this case (saw my cuz playing that part so I kind of know what i"m talking about lol) it was his way of stopping him. Since Solomon can't really die and the electricity can keep him going as long as he's "alive", what is death to us is like a knockout to him.

Or I may just totally be wrong and need to shut the f*** up. lol

Every time I think of Solomon Grundy I think of that episode of Justice League where he befriends Hawkgirl and calls her bird nose and then dies in her arms at the end. So sad.

No. It's just stopping him temporarily.
