How do the members of the Super Suicide Society of the Summer Session take to the creation of blitzball?

As the two founding members of the Super Suicide Society of the Summer Session, Gene and Finny successfully round up more boys to become a part of their secret society. Though Gene hates the jumping ritual that begins each of their meetings, he participates without protesting, as he is powerless to challenge Finny's love for physical challenges. It is Finny's obsession with sports, against the backdrop of war, that leads to the creation of blitzball during the summer of 1942.
Blitzball is a sport invented by Finny in reaction to his disappointment in the summer session's mild athletic programming offerings. The sport of blitzball is very physically aggressive, much like the German blitzkrieg approach to warfare for which the game is named. Individuals playing depend on themselves rather than on a team, and the opposition is basically everyone else. Winning is not really the point of blitzball, which means that the object of the game appears to be the act of overwhelming the others with an attack by medicine ball. Blitzball is extremely well-received by the other boys.
The game keeps thoughts of the war on everyone's minds, which is part of why blitzball becomes so popular. It allows the boys to engage in their own innocent version of warfare as war efforts gather momentum during this summer of 1942. Finny himself proves to be an excellent blitzballer, overpowering others and leading others to similar acts of aggression. In this way, the peacefulness of Devon School is interrupted, making it more war-like and a more accurate reflection of the outside world.
