Transhumanism and assisted suicide

I would identify myself as holding many trans-humanist values and beliefs. That death and dying are not desirable and that it should, like smallpox, be eradicated. It also occurs to me however that I hold the belief that assisted suicide can sometimes be the right course of action. I can justify this sufficiently to myself, but I have a history of being a sophisticated arguer, so my ability to convince myself isn’t great evidence.

Are my beliefs incoherent? I look at both issues and they both still feel right (I’m aware this does not make it so). Are these beliefs contradictory (and if so how)? Or are they justified by some hidden assumptions that I can’t seem to acknowledge explicitly?

I get the idea that this is probably borderline appropriate for the discussion forum so I will delete this topic if asked to.
