being good and bad could also be an environmental factor, though it is still an issue of genetic inheritance, like you get the trait of your mom or your dad, but kids are like sponge they absorbed so much even those thing we dont taught them, they are able to pick it up on the kids that they play with, television, and the surrounding.
to help your kids be protected, instill proper values, set a good example, teach them to pray, and most importantly let them feel the love=)
love means the unselfish kind of love, we oftentimes hear elders say" ganito ang gawin mo kasi ayokong pagdaanan mga pinagdaanan ko, di yan makakabuti sayo" as a curious kid what is it that makes it not good, so you only stir up their curiosity instead of pushing them away... selfless love is letting your kid understand, so parents, i know it is hard but we all had been a kid before, so we could step in into their level of undertsanding=)
