I don't think that's what he's saying.
The people who have broken the law and committed serious offences need to account for that, and I don't see anyone disagreeing with that proposition, but there needs to be restraint on all sides and a sense of proportionality. Lincoln provided the template if people are wise enough to follow it:
"With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations."
You mean 'winner takes all' Lincoln; that Lincoln?
"A house divided against itself cannot stand."
I believe this government cannot endure, permanently half slave and half free.
I do not expect the Union to be dissolved -- I do not expect the house to fall -- but I do expect it will cease to be divided.
It will become all one thing or all the other.
