You confuse instincts and feelings. But they are not the same things, they do not appear in the same areas of the brain. Most feelings are a byproduct of the neocortex, are you aware of that?
Anyway, what you're doing is absurdly tragic.
Human feelings evolved through socialization, not only competition, and this determined our brain growth to a very large extent (for instance, the ability to perceive a lie was critical). I fear we haven't time to make you a lecture about the contemporary theories of evolution, but concerning the origin of our intelligence, maybe you should look to Nash equilibria, that's just a hint to show you how complex can that subject be when so many factors are so deeply entangled.
