Explain why laws exist that do not impose a duty to rescue.​

Traditionally,our society has tended to grant maximum leeway to individual freedom of choice.Requiring that people help one another in emergencies would infringe on that freedom by forcing people to act when they might choose not to.  Further,imposing a duty to rescue presupposes that there is agreement that rendering assistance is always the right thing to do,which in some cases,it is not.  It might also put the rescuer at risk of harm.
