What about the other competitors who had to touch her liquid shit which she knowingly spread everywhere, who could become seriously ill from that decision? Why does she get sympathy for making other competitors choose to either handle her diarrhea or lose the race, and for making the event organizers clean every piece of equipment she knowingly smeared with shit?

At any point she could have said, "I'm getting shit everywhere, I should stop." Horrendous indifference to everyone else involved
