Ender Wiggin
Ender joins General Graff when he was 6 years old. After a long time of training and battling armies Ender then defeats the Buggers being successful. Ender ws also kind and nice but was also a murderer at sometimes when hye never wanted to kill anyone. "I knocked him out standing up. It was like he was dead, standing there. And I was hurting him." (Page 222) Ender was telling this to Bean when he was attcked by Bonzo the commander of Salamander army. Bonzo then died and Ender felt like a murderer. Ender also killed a kid called Stilson a kid that bullied him. When Ender defeated the Buggers everyone in the world thanked him and loved himfor that. The people of Earth didnt care if he was a murderer. "They didnt blame him for any of his murderer's because it wasn't his fault he was just a child." (Page 310)
Then after the Battle with the Buggers Ender was not happy or satisfied or happy. He felt like the General used him just to defeat the buggers. General Mazer Rackham tolf this quote to Ender "It had to be a Child Ender, you were faster then me. Better then me. I was too old and catious. Any decent person who knows what warfare is can never go into battle with a whole heart. But you didnt know. You were reckless and brilliant and young. It's what you were born for' (Page 298) This meant that because Ender was a child and young. He had the skill to do more things than the elderly people can.
Ender also made this book Called Speaker for the Dead and was a religion that started on Earth "On Earth it remained a religion among many religions." (Page 323). He did all these actions at such a young age. So since Ender is young he had an advantage that some older people didnt.
