This strategic move was designed to quell any lingering doubts and shift the focus away from Kisha. By demonstrating that the patients were being properly cared for, she aimed to move past the incident. If anyone were to be held responsible, it should be the individual who released the zombie, leading to the deaths of five innocent people, rather than Kisha.
However, this oversight was also Kisha's. Some of the patients in isolation or those who were likely to awaken had family members who were deeply affected. Witnessing their loved ones turn into zombies was a devastating blow that no one could easily bear. As a parent, the man responsible might have clung to any possible way to save his child, even at the cost of others' lives.
