That is absolutely no excuse for the reaction. "Oops, my bad!" Everyone, media, Bluemoon, already condemned that this was a deliberate act, that the Hospital was an intended target by the IDF, but based on what evidence?
What evidence was being discussed that Israel was the culprit aside from a statement by Hamas/Palestinian Authority and footage of the burning hospital, which now looks to have been the car park. Refuting Hamas fighters raping women despite testimonies and video footage. Condemning Israel to have intentionally bombed a hospital based on a tweet from the group that hates them, instantly.
No-one wants to discuss or think about any possibilities, they only want to condemn and spread more hatred and anger towards one party or the other. People keep saying "things need to calm down", so do it, and wait until all facts about an incident are gathered before reaching a conclusion.
