Being spiritually advanced

[Reaper]

Well, lots of people regard Jesus as a high example of spiritual advancement, yet he murdered one of his playmates in anger, so I'm guessing behind the veil of forgetting anyone is prone to any sort of error.

Jesus also recognized his error and spent the rest of his life letting that moment motivate him toward higher and higher heights of spiritual purity. Ra said that Jesus' karma for killing his playmate was absolved when he forgave those that were murdering him, thus I think this implies that Jesus saw his reflection in those doing the murdering. In forgiving them he forgave himself.

One of the reasons wanderers come back to third density, aside from the obvious intent to be of service, is that the intensity of catalyst allows for quicker polarization. So I would say that lives lived in third density can definitely contribute towards one's overall harvestability. I think it would be hard to generalize what exact degree of harvestability can be obtained, however. That has to do with how far the individual can walk along the stairs of light. It is entirely up to them.
