I'll remember him mainly as the jerk who pardoned Nixon
The Nixon pardon took guts- and it was the right decision. It's not as if having Nixon rot in a prison cell for the rest of his life was going to solve anything.
RIP.
Punishing him?
Spare me your barbaric views on justice; the man became a disgrace and is near-universally regarded as a terrible President solely because of Watergate.
"But I should get away with killing him because I have suffered enough from being THE WORST PRESIDENT EVER."
EDIT: Sorry to hear about your grandmother, Tweed...
