Zero was unimpressed here there was a grown man who was no better than a little child, making empty threats that he couldn't keep,nothing he said even made sense and he just plainly contradicted himself
"You said "you have no right to tell people what they should and should not do" and then continued on to tell me to be quiet now if I'm not mistaken you told me what to do therefore your whole argument is invalid since you can't even make sense, go on keep acting like a child. All you did was pick off things you wanted in what I said without taking everything into context so that you could react and act macho but instead come off as a two year old." he said. He was shocked when he the guy's eyes started glowing not cause of power but because the same man believed it was a good display, glowing eyes? really? You find that in children's toys but he would let it go, he had already made his point. 1 done, 1 to go
"Although I don't take to kindly to threats" he paused taking a deep breathe "However I have to admit even I have been childish and in turn disrespected Master, for that I am sorry. For this is a sad occasion even the heavens themselves openly cry for what we have lost, I will at least remove myself from the situation" with that he went and sat down, for the rest of the funeral he would at least be quiet. More had happened but nothing else needed to be addressed.
