I'd prefer a world where we don't have death row.

A world in which we have to grant people arbitrary and unchecked power to overrule a justice system we can't trust, and can only hope they happen to be incorruptible, doesn't seem preferable.

Power of pardon could be limited in many ways, for example commuting a death sentence to a prison sentence could be allowed. Or commuting a long prison sentence to a shorter sentence, with some lower limit. It's not binary.
