Yes I chose to watch it and now after watching it I think that there should have been some responsibility taken to remove it.
Or, you could take some responsibility for the bad choice you made. Nobody put a gun to your head and forced you to watch it. Your complaint is the equivalent of a child who wants to ban all use of fire after having burnt himself despite being warned of its dangers.
I also like the way you passed the buck to that mythical "somebody" who you say should have done something about the video. Why don't you do something about it yourself? Besides raging on the internet?
It's shocking how little you value your freedom of choice. Trading away your right to access information (note- I said access, you can always choose not to exercise that right by not clicking on the video) in return for the warm safety blanket of censorship protecting you from discomfort.
And best of all, because of your own personal discomfort, you feel that it is all right to enforce the same restrictive censorship on others who may not be as weak stomached as you, and to strip them of their freedom of choice.
