Seems like he was confused, unsure what to do. Can't say I blame him, would have been a crazy situation to be in.
There is some argument that both he and Huber were victims of circumstance (i.e. they would've had justification in trying to stop Rittenhouse had Rittenhouse not had a legal reason to perform the first act of shooting Rosenbaum).
Having said that Grosskreutz demonstrated on cross-examination to be a compulsive liar and had a concealed weapon without a permit so it's not as if he was innocent in the whole chain of events.
