My favorite episode of "The Rebel" was an early one where Johnny Yuma was hiding in the overhead of Wilmer McLean's house. He was going to kill Grant, but when he observed how fair Grant's terms were he didn't go through with the dastardly deed.
By the way, you can do a grave search and come up with Nick Adams' grave. He's got a silhouette of his kepi on his tombstone, and I think it even calls him the rebel.
For his soul's sake, hope that was just referring to his TV persona, although I don't believe that suicide results in damnation if one is truly a believer.
