We are the universe experiencing itself subjectively.

Whether or not you care is merely 1 opinion in an endless universe.

I care and I think others should care.

That is the power of free will granted by our alleged gods.

We are those gods.

We choose the design.

By your logic, I should kill someone today because I feel like it. But someone will care because humans are so precious. What makes us so special? According to you it's nothing, and I'd agree. So perhaps I will kill today, because I feel like it. Then I'll post about how the law should favor my decision because all life is equally worthless.

Will keep you posted.
