The “nineteen” change during the Tull section is actually something “Gunslinger purists” point to as a negative change in the revised version, as it makes one of Roland’s actions a bit more sympathetic than it originally was. I don’t think it was on the same level as the Han/Greedo scene (and having access to Roland’s internal thoughts during the scene keeps it a pretty despicable thing for him to do, even if it was doing the other person a favor in a cosmic sense in the revised version), but it’s somewhat similar.
