Agree. Nearly all Greek manuscripts read splanchnistheis, 'moved with compassion.' One early manuscript, Codex Bezae, and some Old Latin copies read orgistheis, 'moved with anger.' Scribes were likelier to soften anger than to add it. So some editors see the rarer reading as the harder one, and possibly the original. Others see a slip or a scribe echoing another passage. The standard editions print 'compassion.'
It shows how textual critics, the scholars who compare manuscripts, reason, and where that reasoning runs out. The harder reading is often the older one, because copyists tend to smooth rough edges. But that rule doesn't automatically beat the many manuscripts on the other side. Most translations print 'compassion' and footnote 'anger.'
