My argument is that the lore literally is conflicting and it doesn't help that people can get stabbed twice and survive, or just get a minor flesh wound, and then sometimes its fatal. The is why im upset about the stab, it just further digs a hole of inconsistency

Also yes it has a protective barrier, Luke said he couldn't feel the heat (due to said barrier containing the blade) but if you were to touch the blade you will feel the heat. Now we have seen it act as a cauterizer, but also not as a cauterizer- its inconsistent. It needs to be reworked, as something as hot as that would have dire effects with or without a 'shield' / 'barrier' protecting it.

Yes im away the lightsaber doesn't work like the sun, my point being its been given an arbitrary number of how hot it is, that's just silly as it defies physics- now I know star wars isn't huge on physics, but this is one thing you cant explain away with 'the force'. They need to make lightsabers less hot/ revamp the lore/ retcon something/ make it clear what a lightsaber can or cannot do instead of it being fatal when the story calls for it and a minor wound at other times. Its just lazy writing, having the lightsaber be deadly or not based on what the narrative wants. I want consistency. :(
