I don't want my brain replaced (unless by choice)

A rather vacuous statement, no?

I felt guilty gunning down JC and his brother, but it seemed the least wrong (according to my preferences) thing to do.

Isn't human nature funny* that we have qualms about behaving immorally in a sufficiently realistic simulation, yet can hear cold numbers about enormous real disutility (genocides, natural disasters, etc.) and feel nothing? That's speaking for myself incidentally, not casting aspersions on you.

*(where by "funny" I mean "designed by a blind idiot god", naturally)
