Traumatic experiences in childhood often have long-term effects  on a person’s ability to trust, to form close bonds with others, to be honest. Let’s just apply a little psychology 101 to this needy disturbed, dangerous when wounded guy who’s constantly in the news.
His father was known to be a psychopath. He was a famously hard charging judgmental workaholic who parlayed millions of dollars in government grants and his own great business acumen, and willingness to take risks to keep and pass on every dollar of his money, into a billion dollar empire. The father had little use for his young fuck up son as he was grooming his charismatic oldest son to succeed him. Imagine the psychopathic father’s disappointment when he learned that his heir apparent was not a killer, didn’t have what it takes to take everything from everybody by constantly fighting to the death. So the much younger brother, an incorigible bully with limited smarts and very poor people skills, was eventually chosen and groomed to be a killer like Dad.
You don’t get much love from a psychopathic father, the best you get is approval when you carry out his orders. It’s a hard life for a sensitive young person.
When that sensitive young person was in his period of most intense need for his mother’s love and protection, before he was two, his cool, slightly distant and distracted mother became ill and was out of the house for many months, while her youngest son cried for her and got disgusted looks from psychopath dad when he got home from a long day of making the world in his image.
In other words, the time when this kid most needed love, understanding, appreciation and guidance, he was left alone and made to feel weak because of his whining. Is it hard to understand the kind of adult this hurt little boy would likely grow up into?
Imagine his relief a few years later when he got a younger brother, someone he could take out his frustrations on by tormenting every day. Kind of restored the little fucker’s belief in God.
Look at the rest of this now widely adored, widely despised, infamous, beleaguered rich reality TV star/F POTUS. You can draw a straight line from his early childhood injuries to his total war against anybody inclined in any way to contest his will.
And we are all, here in the United States and worldwide, much the poorer, and our lives much more precarious, than they were before this twisted creature came onto the world scene to prove to his psychopath daddy that he’s not a loser.
