Your role in your lineage

[Vampyr]

I often wonder if this "guilt" is tied to the social pressure to carry on the line, or more biologically based in our animal need to reproduce in order to carry on as a species.

Either way it's not a big deal. It isn't like you're killing off an ancestral line of organisms that dates back to some microbe that crawled out of the primordial ooze.

Actually you are.
