WWE is a public company trying to maintain a positive PR. WWE is an active partner with Susan G. Komen and various other social organizations for raising awareness and funds to battle cancer and other deadly illnesses. WWE also is an active partner with Make a Wish - which grants the children with unfortunate medical conditions with a wish. As a matter of fact, WWE Superstar John Cena holds the record for the most wishes granted by a single individual - with a mammoth total of over 500 wishes.
With Roman Reigns successfully fighting cancer for the second time, WWE would be looking forward to using Reigns to create awareness among the WWE fans about deadly diseases. Reigns can be a huge inspiration for people suffering from unfortunate diseases to take the bull by the horns.
