If only he’d shut up and calculate, he’d realize that to prevent the largest amount of suffering he should dedicate his life to researching magical means of granting immortality to everyone, like the Philosopher’s Stone.
Granting immortality is not the same as preventing suffering. Maximizing life span may in fact maximize the opportunities for suffering.
Future suffering or death must be discounted to provide a present value. It is more valuable to save a life now than to save a life a year from now, all else being equal.
Harry would also have to consider opportunity costs and the likelihood of success. He knows that dementors can be killed now. Finding an acceptable magical approach to immortality is less certain, and may actually take more time to develop than a non-magical approach. Harry’s optimal approach may be to kill dementors now, research the nature of magic, and to wait for muggle science to find immortality.
I question the extent to which the two goals have to be juggled in any case, since he already knows how to kill Dementors, and isn’t willing to throw his life away to destroy them, which would be the main conflict. Destroying the Dementors is now a tactical issue that need only concern him when playing politics, so the only way it interferes with his transhumanist goals is if his politicking interferes with his research more-so than it would have if he weren’t doing it with Dementor destruction in mind.
