I can't answer why they would do it, but I don't think it's unusual for these people to knowingly strike civilian targets that they believe will have children present. In the famous Pete Hegseth leaked Signal chat, they were discussing bombing a residential apartment building in the middle of the night because they thought a single target was there visiting his girlfriend. Obviously that carries a high risk of killing children, and in that particular case the Secretary of Defense and Vice President were intimately involved and celebrated after learning that the building had collapsed. If those at the very top are willing to move forward with bombing civilians asleep in a residential building, I have to believe that everyone below them in the chain of command is expected to follow their lead.

No evidence has shown up suggesting there was some sort of compelling target in the school. As foul as Trump and Hegseth may be, they aren't cartoon character villains. The Occam's razor explanation is that this was an intelligence failure and a tragic mistake.
This is very different from targeting civilians as a goal in itself, which is what it would have had to be if this was not just negligence, but intentional, as GP suggested. Parent correctly points out that there's both no political incentive for that, and that it's not realistic from a psychological point of view, given reasonable assumptions about human nature.
