I vote NO.
What if the Daleks's historic rampage of murder had in fact stopped a number of potentially worse and much more harmful beings from coming into existence? If not for the Daleks's, these other foes may just have grown up to cause the universe much more destruction then the Daleks would have ever done if they had been left alone. I think they call it "The Butterfly Effect". I am sick of people involving themselves in other peoples lives (and death). Mind your own darn business, Doctor whoever you are!
