Did film director Stanley Kubrick die of natural causes or was it orchestrated, and if the latter, why was this done?

Kubrick did die of natural causes. It could well have been orchestrated had there not been inroads made to contaminate his thinking and darken his perspective. That is evident from the direction his film work was taking. They were able to get a handhold and then begin to manipulate him to darken his thoughts and his inner beliefs. That, as you know, is a slippery slope. So the film, Eyes Wide Shut, and its celebration of Satanic practices is very telling in this regard. There is no upliftment, there is only non-divine pursuits and individuals with shallow existences seeking to obtain their own personal enjoyment and a selfish and narrow pursuit of pleasures of the flesh. So having made those inroads with corruption, there would be no need for him to be sidelined through arranging his demise, he had essentially allowed himself to be sidelined already.
