text_A: More than anything else, Dumbledore has a deep capacity for love, frequently reminding Harry that love was the greatest magic of all. Dumbledore believes in the good in everyone and insists on giving second chances. The greatest example of this is Dumbledore's relationship with Snape, in whom Dumbledore is willing to place a considerable amount of faith because he showed remorse. Dumbledore is highly perceptive and emotionally intelligent; his knowledge of a person's true personality goes beyond simply being a good judge of character. This is never more apparent than in his complex insights into Voldemort's psyche, which he pieces together with Harry to deduce where Voldemort's horcruxes are hidden.
text_B: Does Dumbledore have correct insights into both Snape and Voldemort?
YES.
