4. Yoda explains anger
When Anakin is in front of the Jedi council, they see right through the young boy. Without any training up until this point, he’s unable to hide his thoughts and calm his emotions – though he does put in good effort.
When Yoda confronts Anakin and asks if he is scared, Anakin says no, but the council already knows differently. Anakin misses his mother and is afraid to lose her. He doesn’t understand why fear is a bad thing though.
"“Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering.”"
In four sentences, Yoda carved out Anakin’s life story. He went from being afraid of a number of things, but especially losing his loved ones like his mother and Padme. That fear of that loss and eventual loss led to anger, which then led to his hate of all things Jedi because they couldn’t save his mother or Padme.
He spent many years suffering after that as Darth Vader and only until he finally had his family and was able to save his son was he able to feel redemption.
Yoda tried to explain how it would all happen, but as a young boy, he couldn’t see that. Instead, it led to the Dark Side.
You could even take quote and apply it to others of the Star Wars universe including Dooku and Kylo Ren. Their path to the Dark Side was laced with the same emotions.
