Neither. I don't think life or death is particularly liberating or dominating, they just are. Being born is largely beyond our control, dying is inevitable.
I suppose I definitely do not see death as "a dominating force to be fought by any means necessary," and the knowledge that I will eventually be dead can be a catalyst to further action (if we accept that death is coming then why not act as if we have nothing to lose?), but realistically, as much as it does that, I like being alive, and I don't go out of my way to do things that likely shorten my time among the living, it is more that, at least sometimes, it doesn't prevent me from choosing to be a part of situations where death somewhat more likely than, say, sitting in an office.
