Yes, also it would appear that LHO’s first plan to shoot Walker would have involved his revolver (which he ordered well before he ordered the rifle). Using the revolver would have necessitated a close encounter with Walker. And due to the close proximity, LHO could likely have been killed by Walker’s protective forces. So, it would appear that he was willing to give his life for his cause…
I believe that Oswald pulled out his revolver at the theatre because he expected/wanted to die, suicide by cop. This suicide mentality goes back to Oswald's initial failed Russian defection when he hacked into his own wrist creating a wound which required five stitches. Oswald writes in his "Historic Diary" that "I decide to end it", "Rimma comes at 8 to find me dead", "As I watch my life whirl away", "how easy to die" , "a sweet death".
This Oswald guy was the very definition of a Kook and someone who places no value on his own life imo would have zero respect for the life of anyone else.
