And then the other side uses it as justification to escalate further.
Name the last time a president was prosecuted and you'll have your answer. Trumps lawsuit over presidential acts just forced into the open what was before a gentlemen's agreement about presidential power. Outside of office, I don't think any of the former presidents had a huge drive to commit anything above financial crimes and using their status.
Biden I can not think of anything scaling beyond putting his ego over country when he went for a second term. He clashed with the legal system but challenges in court is typical for the role. And even in that, he choose to comply (example loan repayment) over Trump who rushes to complete his goal before legal can step in (golf course, ballroom, etc).
You're just proving my point without realizing it. I'm not even American, and have no horse in your race.

Please tell me about the time the Biden White House publicly called on the DOJ to prosecute its political enemies or interfere in elections.
If that happened, it should not be hard to find a reference to a public statement or executive order.
