He did, but he was also right. And if his daughter hadn't stolen the worm when Taox tried to kill them, then everything would be different. Or if Taox had just offed the king (or even waited until he died) and gotten rid of the worm, but let the daughters rule, they would've never been forced to flee to the deep and basically become Goa'uld. But then we wouldn't have a story. 😝 Thing is... People debate whether the traveller was right to wipe out a bunch of people for the greater good... Was Taox right to try and wipe out a royal line? It's a complicated thing.
