Yes, bombing Ahli Arab hospital is an atrocity and a war crime. You know it, I know it, Israel knows it, and Hamas knows it. Hamas doesn't have a lot of reasons to intentionally blow up a Palestinian hospital, beyond maybe trying to stage a false flag attack. Israel has more reasons; Israel could have been targeting weapons stored in the hospital or a high value target. But even if Israel did have intelligence that made them think there was something worth striking in Ahli Arab, the political repercussions of striking a hospital would be so severe that I doubt they would pull the trigger. The commenter you quoted was likely thinking something along the lines of "neither side has a strong motive to intentionally bomb Ahli Arab, so the most likely reason for the bombing is an accidental strike. Assuming that the accident isn't part of a trend of accidents, the unfortunate reality of war is that accidents happen on all sides. Thus, it doesn't really matter if it was an Israeli accident or a Hamas accident." Should we investigate and determine if the strike really was an accident? Yes, of course. But we can also predict that the result of that investigation will be "it was an accident", and start to make preliminary conclusions predicated on that.
