Astrology doubts........................…

I have Venus in the 8th. It says a peaceful death. However, I find it hard to believe that everyone in this world who had died peacefully in their sleep had Venus in the 8th. Likewise, everyone in this world who has Venus in the 8th will all die peacefully. ??????????????? I think most people will agree that is very very possible thus making the birth chart once again ridiculous. Is there just a whole lot of other things to consider in the chart? If so, how complicated is it going to get? Enlighten me please!
