President Trump will be fine. Even if he leaves office this month, he still has a leadership role to fill if he wants it. I would certainly say that we do still need him. It sounds like he’s very much ready to soldier on in another role.
He won’t be able to soldier on. They will attack him with law suits and criminal prosecutions from day one. And do the same to his entire family and anyone who worked closely with him in his administration. They need to make an example of him so that no one else will attempt to take on the deep state.
