You have asked why the MSM was so negative toward Trump. You make the claim that Trump was a great president, he got things done. But you posted something that is very telling,
He doesn't take any side except what will be best for HIM, best for his family... best for America in that order
There is your answer. A president is, first and foremost, a leader. I completely agree with your assessment of Trump's priorities. And anyone with that hierarchy of priorities is, quite frankly, incapable of being a leader. In fact, a real leader would have the exact opposite hierarchy. Country first, family second, himself last. A good example, Gerald Ford. He granted Nixon a pardon. That was not good for him, probably wasn't too good for his family, but was what he needed to do to move the country toward healing after Watergate. It cost him the presidency. He put the country first. Lyndon Johnson refused to run for re-election. That choice wasn't good for him, it was good for the country. And when it came to getting things done, Johnson was THE MAN. Trump had few real accomplishments that he could point to. Gas prices, well hell, his pitiful response to Covid tanked the economy, so hell yeah gas prices went down. Energy independence my ass, we never stopped importing oil. That is a fabricated claim based on numbers, it is not based on reality. True energy independence means we don't import anything for our energy needs. And perhaps we could achieve that if we weren't exporting diesel and natural gas.
But Trump's real legacy will be his inability to accept his defeat, further fracturing an already divided nation. A real leader would have accepted that defeat, even if he thought it was fraudulent, for the good of the country. Every previous president for two hundred years gracefully accepted their defeat. Trump's selfishness, always putting himself first, will be how he will be remembered. He would burn the entire country to the ground, was even willing to order soldiers to attack fellow Americans, just to preserve his position. Absolutely disgusting.
