Why didn't he just kill Suzaku?

Why are you asking this again?

Suzaku just needed redpilling.

Friend/could use his skill

childhood friend whom he still cared for

This. Lelouch considers Suzaku to be his only real friend and is the one person that he would want on his side when he went against Britannia.

Friend
fail-safe to take care of Nunnally in case something happens

Because he was gay for Suzaku.

Because, you never watched Code Geass and it's showing

Because Lulu wasn't suited for the path of blood. I bet he'd have wanted just some pussy ass quiet life with his precious Nunnaly.

I can totally understand this sentiment. They have been friends since childhood. I have been friends with my best friend for 17 years. If in some fucked up situation happens I want to be on the same side. Killing him seems like the literally last option. Means more than blood family ever will.
