Yoda tells Luke he will confront Vader again but he doesn’t request that he kill him.
Ben basically says it’s essential that Luke kills his sole remaining parent.
So in that regard they are two very different kinds of Jedi.
One believes in the powerful influence of inner control and the other believes in martial action, exterior action.
In the end Luke does confront his father but he turns away from the darkness allowing Anakin the chance to Return and defeat Vader and Palpatine.
This doesn’t chime with Yoda of the prequels who on one hand tells Anakin to let go of his Mother and his Wife but on the other hand walks into the Emperor’s office after slaying many brainwashed clones and attempts to assassinate a Sith Lord with a weapon.
It would be better if Yoda didn’t appear in the prequels at all, he is hidden away holding the knowledge that will save the Galaxy he doesn’t need to make an appearence.
