I think you are veering your argument the wrong way. While Views and Votes are relevant when deleting questions the most important factor is the quality of the answers.
When deleting a question the first concern you have to occupy with is: do this answers worth my time? Are they really good answers? Those it leave the internet in a better state that it was found? (the last one is a wording of one of the goals of SO, or more like SE proper)
The only thing that is included in the help centerhelp center about where you should not delete is:
Before voting to delete, please check that there are no good answers; if so, then the question should be flagged for moderator attention as a potential merge candidate. We don't like to lose great answers!
Note, it says "good" and "great", which are subjectives so YMMV.
This means that I shouldn't take into account views or votes? No, it means that views and votes is not really the most important value of a post, but answers. The most pressing reason not to delete a question are the answers they produced, views and votes should be in second plane.
Now my personal take is: views and votes just means they are popular, not that they are particularly useful and shouldn't sway my decision to delete a question.
