You claim your step-son was damaged goods by the age of 2 and then go on to say horrible things about him. It sounds as though he missed out on having the kind of family who would love him and guide him. From what you write, you had very different feelings towards your biological kids and him. That’s really sad. Knowing you are the unloved sibling can permanently alter who a child is going to become. My advice to any parent would be to show the same kind of love to ALL children growing up in the same home.
