Is it normal that i wish an asteroid would end humanity?

Yes because humans suck.

If I were from outer spaceand landed herae nd observed every species on this planet killed its on as well as all other species I would vote to destroy it

What the hell is wrong with you.

Sir, I like shrimp AND lobster, tyvm!

No... Even though life is pointless.

Why do people think life needs a point for it to have any value? Life doesn't have meaning.. The meaning is whatever you make it.

This is an impossibility in the sense that afterwards nobody would know it had happened.

If that asteroid can end all humanity, that also entails that it ends all animal life too. So, no thanks. Man will destroy man with poison and bombs on our own time
