(You're warning your son to keep himself safe, so he doesn't meet the same fate as you) 

I didn’t come back to ask you to avenge me. I came to tell you to let go. I’m dead, no justice or conviction will change that. The only thing to be gained is your safety, and that can only be guaranteed if you leave. Things. Be. 

(You're saying your final goodbye)

I love you so much, Hamlet. More than you could ever know. I hope I see you again someday.
