Trust and susceptibility

I've given trust away so many times for it to be thrown around like a frisbee. Susceptibility, it's our nature. What our subconscious believes as truth isn't always the case. We have levels. These different levels bring forth perception. No individual lives the same. We all create our environments through these levels. Hence our own reality. Why would evolution allow such a heinous thing? To think and be free. Similar to being aggressive and hurting. All manifested from thought. Does being mechanical suit us better? Would life flow more easily if we didn't have the capacity to think ? We wouldn't have the tremendous strain of conscious awareness. Objectively, to be aware means you can identify folly. To not correct such deviations when you have the ability to is not the natural flow of things. To be a star and not emit heat is not natural. So to think and not constructively use it would not be natural, although our thoughts will trick us into thinking otherwise. Trust and susceptibility, very intrinsic ideals indeed.
