If you think you've "converted" from Christianity to atheism, then with all due respect you haven't. What you've done are shed the shackles of a cultural fairy tale. You haven't added or changed anything, only removed a psychological impediment to your clear thinking.
And, to me, that answers your OP. From an individual perspective, clear thinking can be harmful; if you spend all your time trying to understand your mind and your life, you may end up sitting under a tree and meditating, rather than paying bills and making and feeding offspring. From a social perspective, obviously leaders do NOT want people sitting around thinking about what really matter in life, and what is right or wrong, because bowing down to some alpha-male dick and building his castle for him is probably not going to come up top on your list of fun things to do.
