Not saying you're wrong, Julius Caesar committed more than his fair share of atrocities, but do you have a source?
Wikipedia says that Julius Caesar threatened his troops with decimation but didn't carry it out. I asked chatgpt about it and it said that Julius Caesar did order one, but then said no contemporary sources for this exist. It then claimed that Plutarch wrote that Julius Caesar made his troops draw lots, which certainly suggests he ordered a decimation, but I checked two English translations of Parallel Lives and neither of them contain any mention of this. I also asked the not to translate the original Greek, and that also doesn't mention it. The chatbot thinking it happened suggests that somebody has written that it did, but I can't figure out who and where.
You've done much more research into this than I have. I read about it in a biography of him (Caesar: life of a colossus by Goldsworthy), but you're probably right.
