Survival is not selfish because it is considered a natural instinct, imperative to one's life, and it helps to move on and save people's lives. For some, survival is considered a “natural instinct”, and it comes naturally to one, so when faced with a dangerous situation, we often tend to refer to this. Saving others is always the right thing to do. Many factors influence the behavior of a person in a crisis.
Those who survive a disaster should not be criticized. According to a 2004 study, holocaust survivors have developed a habit of storing a large amount of food, having difficulty throwing away food, and even feeling anxious when food is not immediately available.
