The last time someone bled from a lightsaber wound was in the original film cut of The Empire Strikes Back when Luke took an arm off the Wampa, it never happened again. The blood has since been cleaned off in every re-release of the original series except A New Hope.
In the old EU, it used to be that being Force Sensitive was a prerequisite for wielding a lightsaber because they were often just as dangerous to the wielder as they were to the enemy. No one without some level of precognition or Jedi/Sith training could use them in combat. It was the explanation behind why they were so useful and dangerous but also so rare, carried only by Force users trained in the Jedi or Sith arts.
The three groups in Star Wars that use lightsabers are:
A) Fully Trained Jedi/Sith Force Users
B) Nascent or Partially Trained Force Users, Padawans, Ex-Padawans, etc.
C) Droids with proper programming.
In a setting context, the lightsaber is a main reason why your average
Sith or Jedi can suddenly transform into a one man wrecking crew if not
It fulfills both ends of the combat spectrum. It is exceedingly useful and efficient in the right hands and it is intimidating if not downright scary by reputation.
For most of the galaxy, the Force is difficult to quantify and understand. A plasma blade that can slice you and dice you into six different pieces while simultaneously blocking incoming blaster fire is much easier to get behind.
And while, yes, the cauterizing of the wounds means that someone who suffers a lightsaber blow is more likely to survive, it doesn’t mean the experience is pleasant.
Many writers have a mistaken view that death is the worst thing that can happen to a person and end up having heroic characters commit horrific atrocities as a result, doing more damage in the long run than they might’ve if they’d just killed the other character.
The lightsaber is the three section staff of the Star Wars world, really awesome if you know what you’re doing and liable to give yourself a concussion if you don’t. (Or, in this case, lose a limb…or several.)
There’s no getting around burning yourself with the nunchaku lightsaber though, that one is just dumb.
It’s a standard issue part of the setting and most of the wounds received from similar types of energy weapons like blasters are also bloodless. This acts as a backhanded setting justification for how the series can be so violent while sneaking itself past the sensors.
