That's like ~40% of the deaths in the current gaza war, except over just 2 days instead of 2 years.
"We killed about 80,000 people by mistake" isn't the exculpation you think it is.
This is ridiculous.
I don't want to be a Hamas apologist; they're certainly brutally cynical enough to use civilians as shields, but in the case of Gaza, what else would you expect them to do?
Urban areas are strong defensive structures, and 75% of Gaza is urban. Where else would you expect them to fight? It would be unrealistic to expect Hamas to take on the IDF in open farmland so they could be annihilated by Israeli air power.
If party A is using a human shield, and party B decides to kill the human shield to get revenge on party A, then who is culpable for the death? I don't think it's an entirely obvious answer. I don't think anyone who can easily and automatically put all the blame on party A or B has really thought it through.
