During his successful revolution with Castro in Cuba Che became heated on his beliefs. From his work with Castro they succeeded in gaining control in Cuba. Some would say during his multiple revolutionary attempts that he pushed these beliefs on some who didn't agree, while others saw him as a hero for all the people in South America and their struggle.
Che believed that everyone should be treated as an equal despite how he sometimes went about it. Whatever the case, it is undeniable that Che worked hard in the ways he thought were correct for the less fortunate people of South America.
