That depends on your vantage point.

If you accept the mainstream Palestinian viewpoint, i.e. the one that endorses Hamas and the Simchat Torah massacre, there is no such thing as too many, because every Palestinian death furthers the jihadist cause of demonizing Israel.

If you accept the mainstream Israeli viewpoint, all of these deaths were unnecessary because they directly resulted from an unprovoked onslaught against innocent civilians, and all of the casualties could have been avoided but for the Gazan misadventure of October 7th.

I'm not sure which camp GP subscribes to, however.
