"Dr. Wittstein and his research team found that some people may respond to sudden, overwhelming emotional stress by releasing large amounts of adrenalin and other chemicals into the blood stream. These chemicals can be temporarily toxic to the heart, effectively stunning the muscle and producing symptoms similar to those of a typical heart attack: chest pain, fluid in the lungs, shortness of breath and heart failure. However, there are no further similarities between "broken heart" syndrome and cardiac arrest. Closer inspection using blood tests and magnetic resonance imaging scans failed to show the typical heart attack signs, such as irreversible muscle damage and elevated levels of certain enzymes."
If that happened, it would have been avoidable; it doesn't necessarily mean he was sickly and this was the straw that broke the camel's back.
(Aside: I wonder if anyone here would think comparable things of the organizers of a surprise party, 16 years after it's published in a medical journal that they can be fatal? What if the birthay person was known to hate surprise parties? Anyone calling for a death penalty or years in prison?)

Swatting has a predictable risk of mortality thus the criminals don't get off morally because their victim died a different way than expected.
I haven't seen a claim that the perpetrators expected the man to die - didn't they want to harass and scare him until he gave up his Twitter handle? If he was dead they'd have no chance of getting access to it, therefore they likely were not planning for him to die, right?
If Barney Fife showed up to kindly ask you if you were ok you would have been swatted just not very effectively.

Google reverse image search for that suggests a search term of "fbi swat team" and first result is a wikipedia link to "FBI Special Weapons and Tactics Teams". The picture is from the Wikipedia page on swatting which says it is "an FBI SWAT team during training". https://en.wikipedia.org/wiki/Swatting
If you shoot someone, we don't say that technically the bullet killed them not the person who fired the shot.
