> If Yoda deceives Luke that saves TLJ from having Yoda actually mirror Kylo Ren, but it doesn't explain the fire and lightning (Sith tools associated with hell imagery) nor does it resolve the underlying problem since deception is also Dark Side behaviour.... It comes down to intent. Fire, lightning, and destruction aren't relegated to the Dark Side of the Force. Jedis have always had their share of destruction and murder. They were a literal army during the time of the Old Republic. Obi-Wan and Qui-Gon's behavior in the first scenes of TPM show this firsthand. They were sent to the Trade Federation to intimidate—not a very noble thing to do on the surface, but it was in the greater good. There have been innumerable essays and analyses understanding how the two sides differ, but the one that's always stuck with me is that the Jedi are at their core more of a guiding force, whereas the Sith are a controlling force. Everything the Sith do is for their own greater good, whereas the Jedi will do things (even kill, or destroy) if it leads to the greater good of others. And, in this case, the destruction of the temple leads Luke to understand that old books aren't what are important. No one died when that tree was destroyed. And it may very well have been what pushed Luke to self-sacrifice and save the remnants of the Resistance. That seems like a very "Jedi" thing to do (IMO).
