Tigers, indeed all animals, do not favour violence as a means of settling scores. When animals fight, it is with the intent to kill and with the understanding that they may be killed. A clash is costly. And so animals have a full system of cautionary signals designed to avoid a showdown, and they are quick to back down when they feel they can. Rarely will a tiger attack a fellow predator without warning .... It will appraise the situation. If it decides there is no threat, it will turn away....
