Thanks for the ping, RnMomof7.
Regarding babies, skull stomper, watch any newborn to 2 year old. They display anger when they don't get what they want. We must train them to control themselves when they are of the age to "understand" temper tantrums are wrong. Their angry displays do not make them evil children, merely evidence that there is a badness in them already which must be brought under control and done away with, if at all possible.
Left to "become" who they are without correction, we see these children later, in pre-teen and teen years (and even younger), as tyrants and/or manipulators...only concerned about and motivated by their own selfish wants and desires without regard to others' needs. These little tyrants are children who have not been taught to deny themselves or to control their wills.
Humanist psychologists would not have parents constrain babies/toddler/teens because their "self-esteem" may be injured if they are told they've done something "wrong," they don't "measure up" to a moral STANDARD of behavior. To humanists, "wrong" is relative.
I think that's another reason why you see so many kids doing so many things morally wrong today (as opposed to mischievous behavior). They have not been taught to deny their selfishness, have not been taught to control their will, have not been equipped to understand moral right and moral wrong. They are "standard" free, left to forge out their own tyrannical versions of right and wrong in our "if it feels good, do it" society.
