That was not sarcasm, which generally requires words used in contradiction to the normal meaning. E.g., if somebody makes a dumb mistake, the response, "nice work, Einstein" would be sarcastic. This was at worst mocking, but it wasn't ever hyperbolic, given that the what was written was a literal description of what the guy did.
Regardless, you haven't answered the point about the quote. "Judge not lest ye be judged" does not mean we have to empty-headedly refrain from any sort of moral criticism. In context, it's about hypocrisy, reminding us to apply our standards to ourselves as stringently as we do others. I think it's only appropriate here if tsigo somehow indicated he would happily endanger his own children, which I don't see any sign of.
