[Star Wars] I'm a relatively strong Jedi that survived Order 66. I managed to sneak into Vader's Castle at Mustafar. He's now chilling in his Bacta Tank. Can I easily kill him while he's out of his suit?

I know that there are Royal Guards inside, but I do not assume they will be much of a problem.

Vader can sense other Jedi from pretty far off. He knew obi wan was on the Death Star and that luke was on the shuttle going to Endor. You didn't sneak in, his job is hunting and killing Jedi. He let you in.
