Haunting deleted scene from Iron Giant.

I wonder why the first instinct is to fight other intelligent life ...or is this just a trope of fiction, that I've seen so much, that I think is how the real world works now too..?

Evil? No. It shows he was designed to destroy. But it doesn't say that is all that he is. The whole point was that he could be more than that.

Well, he was designed to be a weapon 🤷‍♀️

It was Hogarth who made him realize he didnt have to be 🤗
