Using terms like "deep state" isn't helpful. When I first heard that he is pardoning members of his own family, it struck me as disgusting. Then I did a little research. These are pre-emptive pardons and they apply to people that Trump has already threatened to take revenge on. He is a vindictive man, he has previously stated that he could have sent Hillary Clinton to jail, and that he didn't only because he is a nice man. Both claims are false. He will try to take revenge on his critics, General Milley referred to Trump as a fascist, Fauci stood up to Trump, others attacked Trump too.
Whatever you think of Trump, this is a man who lies habitually, and he was found guilty of sexual assault, and fraud. Remember he encouraged the storming of the capitol, and for a long time falsely claimed that the Trump Biden election was stolen.
I suspect many people are very frightened of what Trump might do to honest people out of sheer narcissistic revenge.
