Star Trek II: The Wrath of Khan (TWOK) was by far the best Star Trek movie. Based on Moby Dick, Khan believed from hell's heart that Captain Kirk killed his wife, so he pursued him with hateful vengeance, even with his last breath.
Of course, the plan was foiled by Spock who sacrificed his life for the despised Kirk.
I was thinking specifically about Spock's Christlike sacrifice when I remembered the first time I heard the phrase, "Good deeds never go unpunished." My high school choir director uttered these words, and then later went on to heroically save a drowning kid from the Delaware River. (Go figure.)
This phrase was shortsighted in the final analysis. TWOK showed this in that Spock's true self lives in Dr. McCoy. This could obviously indicate that we live in our friends' memory, but I think it was deeper than that. Since Spock's Katra could be passed onto another, was it possible that his Katra could live on in the Ultimate Mind, God? I think that was a distinct possibility.
So, ultimately, good deeds in love could assure our infinite existence in the Mind of God.
