I can see you have a bit of a point, but... the 2nd most evil bloke you refer to was his father, a man he'd never known, and Luke could sense that there was good in him. He was right. He also wasn't actually going to murder Ben, but before...
First SW film I haven't seen on release day since Jedi, as it looks odd. The main character just didn't seem anything like Solo in the trailer. Was he in the film?
