Edison was a conniving asshole.
He’s behind the use of the electric chair.
He also had stray dogs rounded up and publicly electrocuted to show the danger of AC.
He electrocuted an elephant as well.
He had patents filed in his name that were the fruits of men working for him.

What people refer to as "bats in the belfry" sometimes is just a set of priorities that are wildly different than most. I don't think Tesla gave a damn about money, other than as a means by which he could continue his experiments.
