Defiant and almost stupidly brave, Cato never gave in. After Katniss blew up the supplies he unleashed another side of him, a side that convinced Katniss he was not completely sane. Determined to win, he did everything he could to achieve his goal. He didn't care who he killed in the process, whose lives were spent, as long as he came out alive--which is the point of the Games. Cato is a Career who killed people, innocent or guilty.
