I have always thought that Reed was a bit of a moron to have all those experiments right around his family. Sure he's a scientist but... there's a limit and rule about bringing your work home with you. But, the death of the Human Torch was just a case of Johnny being the hero we all knew he was. He made a choice. Sure, Reed had his hand in the tragedy but Torch made the decision. I'm sure he blames no one and was proud to go down fighting.
