The answer: It sounds weird, but insects can definitely be good for you because they're a good source of protein and they're low in calories, says Gans. It helps to compare insects to other well-known sources of protein, like chicken and eggs. So here we go: A typical serving size of crickets is 3.5 ounces. That portion contains 13 grams of protein and 121 calories, says Gans. In comparison, that same amount of eggs (about two large eggs) contains the exact same amount of protein and only slightly more calories (154).
Dumbledore and Snape did have a plan in advance in which Snape killed Dumbledore. It is revealed in the 7th book. Dumbledore is really dead. However, in the 7th book, harry dies temporarily and meets dumbledore in like a limbo dream world. its intense.
Snape would never come to love Harry because he sees James in him. Similarly for Harry, Snape was the man who betrayed his parents but on the other hand if not for Snape he would have been probably dead. So it is kind of a loose end to the series. Also Dumbledore was the only one who knew Snape's true allegiance. Even if he had survived he would have had a hard time convincing wizarding world of his innocence seeing his past record and Dumbledore's murder.
