Being a victim of any regretted tragedy is very romantically glorified! May be that's the reason why you observe majority prefer that state - deep indulgence of sympathy and tears. It more often renders people mixing tragedy with regrets without even understanding the difference between the two. It does create an impression of - "So long as it generates sympathy and sulking, its perfectly fine!"
Tragedy may occur due to external forces. Which leaves us with only acceptance of the same to move on. There are very little things in one's control when it is a tragedy. But the one thing in your control needs to be exercised in full form - accepting it as your foundation.
Regrets occur due to wrong choices. As Mark Twain says - "Twenty years from now, you will be more disappointed by the things you didn't do than by the ones you did do..." And that is no tragedy! Not being able to make the right choice, failing to take the onus of one's choices and finding answers within oneself is the way to not live with regrets.
Mixing these two would be a real regretted tragedy, wouldn't it? But if this distinction is clear, a greater realization dawns upon us - "We being extremely privileged". That enables real acceptance and moving on... letting go... taking off...
