The Clinton Foundation, and the Clinton's themselves, are tied into some shady folks. A lot of the "bodies" on the clinton body count, if they were actually murders, were done by people with more skin shutting them up forever than the Clintons.
Hilary & Bill participate in some really complex & well obfuscated scandals. They have a long history, all the way back to Governor of Arkansas, of figuring out ways to get money and muscle opponents that leave JUST enough plausible deniability. And sure, taken one by one, you think 'oh come on'. But it keeps happening. And then bodies of people with potential dirt on the Clintons DO keep turning up, and it does make one wonder.
tl;dr
They are probably at least indirectly responsible for some folks turning up dead (will no one rid me of this troublesome whistleblower) but most of the Clinton Body Count lists are full of obviously unrelated deaths. Which is a shame because it makes people ignore the real headscratchers.
Edit:
For example:
Stanley Huggins. He was a Memphis Lawyer, died of pneumonia and his office was broken into and record stolen. Now, he was involved in the White water investigation, but had other dealings in Memphis as well. Its very well possible Stanley had criminal clients very concerned about record leaks, and they went in to destroy records. But then his medical records were sealed by Attorney General Janet Reno. Why would the Attorney General seal medical records for a death by pneumonia?
On the other side of the scale you have David Drye who died in a small plane crash. While there are a bunch of ways to sabotage a small plane, there are also a lot of ways for you to just die without any need for spook involvement.
Also the case of John Ashe, who did likely have dirt on the Clintons, but he was arrested on bribery charges that were not directly related to Clintons/CGF. His trial, however did concern people more connected and ruthless than the Clintons. If he was killed, it was almost certainly by the very literal criminal gangsters he dealt with, not the pubic Clintons.
And in the dark grey middle ground you have guys like Klaus Eberwein, a Haitian official who made no secret of his dislike of the Clinton Global Foundation*. However while he had expressed willingness to testify against the CGF under oath*, the trial he died during was about missuse of PetroCaribe funds (Venezuelan Oil Program) and nothing about CGF. The Clinton's likely sleep better knowing he's unable to testify against them and their foundation, but his death didn't do them any direct & immediate good.
*And this may need to be taken with a grain or two of salt, as in his eyes it seems the real crime the CGF committed seems to have been not giving him any payoffs or kickbacks, and he felt left out & disrespected. It is very likely he could have been bought off rather easily and cheaply, a much more prudent move if the Clintons are as evil as to believed; of course history is full of smart people making obviously dumb moves.
