Humans may see tigers as gruesome, although this is not the case. Tigers may bemistaken for gruesome because they eat humans, but tigers have natural instincts to protect/defend their territory. If a human, lets say a researcher observing wild tigers, enters a tigers territory or if the tiger feels threatened, the tiger will try to be imitating. The tiger will growl, swipe or even 'charge' at the human. If this human does not take action, such as slowly leave the tiger alone, the results may end in serious injury, minor injury panic or even death.
