The god should have just gave him something garbage with that attitude, its not like he died due to their mistake or anything
I'm not so sure about that. They mention how quick he is to change the topic, but when he says "I don't think you can die from that tho" suddenly, look who's changing the topic in a huff? Almost as if delving too far into that topic could look bad? I suppose if this really is the case and it's important enough we'll come back to the issue eventually. If not, I'd agree with Lidquidxlax. He was being a little rude, perhaps, but it was probably a novel experience, he wasn't doing it particularly maliciously, and this goddess or whatever is just doing its job either way. If every person (or entity I suppose) acted childishly in response they people they have to deal with during work, we'd never get anything done.
