[Original Spider-Man Trilogy] Why didn’t Peter immediately explain what happened to Harry’s dad?

From Harry’s perspective, a strange masked man just dumped his father’s corpse on the ground. What was he supposed to think, apart from “Spider-Man killed my dad?!”

Why didn’t Peter just say “Your father was the Green Goblin. He tried to kill me and he killed himself.”?

If he wanted to preserve Harry’s memory of Norman, why didn’t he say, “The Green Goblin kidnapped and murdered your father.” That’s true, at least from a certain point of view.

Because Peter Parker, despite being very intelligent, has extreme trouble making decisions that will make his life easier.  Across all media, comics, TV, movies, Spider-Man can be trusted to make a morally sound decision that will come back to make things more difficult for himself down the line.
