Lyle,
While I do not know you, I consider myself a friend to Ragnar. I only knew him for a short time but I found myself fighting next to him many times. I wish I could say something that would soften the grief, but I fear really only time will heal these wounds. What I can say is this, please do not be ashamed that you were not there when he fell. I fell before he did, but I am told he single handedly held the line of vampires off while the adventurers retreated to regroup. He held an entire wave of foes from attacking the flanks and probably sending many to their deaths. His death was one of the most valiant I have heard of. I don't think he would want you to think of his final act and be ashamed or pained. Rather, I think he would want you to remember his actions with pride.
Peace be with you,
