"amoral"? What s that? Are bacteria killing my cells and undermining my health amoral? Are species whose strong males get to mate with most females amoral for not having a marriage certificate that requires monogamus relationships?
You seem to be saying that a "strong" individual would thrive by being amoral at the expense of the group
Besides not making sense, there seems to be an extrapolation of what I am saying. Where have I hinted "at the expense of the group".
Regarding "weak" and "strong" are used in the only context they can be used, individual/species with traits that make them more or less likely to survive. I don't understand what's so hard to understand.
