On a more serious note, after reading the story, I think his loony side is showing and that there's a good chance he's (at least somewhat) got some kind of mental disorder. And/OR theory #2 (see below).
If he really has had multiple people repeatedly explaining to him what a suicidal farce defending yourself in a murder trial is- then he's going against it anyway and that is a window into the workings of his personality and brain. Freakin' TED BUNDY did this 'defending yourself' shit too, and Waseem likely knows this if he's not delusional or disassociated from reality in some way. C'mon- the guy was the defendant in a trial and accused of a psycho style murder. Unless the whole thing was so painful he consciously refused to listen to stuff about trials and serial killers and stuff- (or living in a cave that allowed him to commute regularly to work in his family's furniture store) then he would have heard about Bundy.
This says A) he mustn't be able to comprehend reality very well, B) he has a superiority complex and greatly overestimated sense of his ability to do something others cannot, or C) he has that sociopath-type faith in his ability to manipulate people like Ted Bundy had.
Theory #2: Maybe because of the way the system works and the idea that public defenders don't know what the fuck they're talking about the way high-end defense attorneys do (a common semi-misconception), he's never been made fully aware of the ridiculousness of doing what he's doing.
If he is one or all of the A,B or C choices, it'd go a long way to explain how he would have been capable of the murders so long ago. And just because you're nuts and killed someone because of your being nuts years ago- it doesn't necessarily mean there's some trail of bodies out there buried in shallow graves or underneath his house either. A lot of (usually mild) sociopath/psychopath types are relatively safe to be around. They are not so delusional to not realize the consequences of getting caught or the fact society deems it 'wrong'. Some may be able to feel guilt and remorse and know themselves that harming others is (at least in part) wrong.
