Two opposing factions can negate each other to leave a nil influence, and this seems likely to be the case when its resting on a foundation of ‘faith’.
I don't think there is much of a real-life debate here. I bet the overwhelming majority of humans (say, 95%) would prefer humanity to continue to exist. Are you really taking the other side of this bet?
If you want to speak of universalizing beyond humanity, what is your case? It makes no categorical sense to reckon our toll on the universe. The universe was fine before we arrived and will remain unaffected if we disappeared. It has no preference. I don't understand your argument honestly, because you have not stated it.
