There is no truth coming from "feel". Our brain chemicals are designed in a way that suits evolution best, not to mention that there is absolutely no consistence in these feelings on an individual level (to a smaller degree) and on the the temporal and cultural level.

And I think if this was indicating a truth of some sorts, the differences morals doesnt sell this idea to me personally.
