Romney only really displays any conscience when he thinks it will benefit him. He made his money via "vulture capitalism", which is buying up undervalued companies and selling off the pieces and taking any pension funds as profits, leaving a lot of people out of work and with no pensions when they retire.
He is opnly criticizing Trum to try to raise his own profile. He doesn't actually care.
In retrospect if Mitt Romney had beaten Obama in 2012, we wouldn't have had Trump. He would've been a moderate Republican president and would've appointed better justices than Kavanaugh and Gorsuch. Democrats would've still probably took House 2018 off year. Mitt would've protected our citizens better for Covid-19. Would've saved 200K lives.
He could have gone fervently with impeachment, or declared no Supreme should be picked until after the elections, but noooooooooo.........
