NFL Concussions
It shouldn’t come as too much of a surprise that repeated blows to the head cause long-term damage. However, the NFL tried its best to cover this up for as long as possible. They downplayed the dangers of the sport and repressed medical studies that proved CTE was real.
This showed a lack of moral compass because they exploited young men who didn’t understand the risk. Then they endured horrific health effects in their later life. Now the NFL is dealing with hundreds of lawsuits because of the lives they have destroyed (via FSP).
