There are people who think it is evil/spooky/creepy to own or fly former military aircraft, too, because of the same type of perception about how it was used.
It is an object -- it doesn't have a memory or a spirit.
My favorite is a former neighbor of mine who had his house broken into and a gun stolen (a S&W 686 revolver). Some months later the police called and told him his pistol had been used in a crime and once the crime was cleared, he could get the gun back.
When he finally got it back -- which was a year or so later I think even after that -- the surface was all corroded where there had been blood on it, and it hadn't been cleaned after the crime and being put into a police evidence bag.
My neighbor couldn't stand the thought that his pistol had been used in a crime and that it was human blood that had damaged the surface...so, knowing I was a firearms guy, he asked me if I wanted it, and when I said yes, he went into a long missive about how it was evil now that it had been used to draw blood.
Although it needed a re-finishing, it sure shot great.
