Does commiting suicide make you non-harvestable?

[MangusKhan]

I don't think Don's suicide can really be compared to the majority of suicides. He was already an older gentleman and had to a large extent completed his life's mission (to bring the Ra material to earth). It is always dependent on circumstance whether or a decision is the "right decision". Generally speaking, I think the entity who dies by suicide would not be harvestable. One who is endowed with the level of faith and perseverance necessary for harvest would not likely die by that cause. More likely is it that a harvestable entity would die by murder than suicide.
