It's been billions of years before I existed, and potentially trillions of years afterwards. I'm incredibly lucky to be aware and thinking, so why should I complain about stuff happening after my spark of awareness has faded?

This is exactly how I do it. In the long run, none of this shit matters, and nothing will be remembered. The planet has rebooted several times in its history, what are the odds that this particular sentient being would be here to witness it? Enjoy the ride while it lasts, make sure any survivors of the collapse remember who the guilty parties are.
