I'm aware that this question is sort of borderline for the rules of the subreddit, because it's mentioning recent events. It's not a question about current events though, but rather a question regarding philosophy of history.

I'm not linking to the news because I've found no english sources, but I can provide a few in italian language if asked.

Facts in brief are: a man took an unexploded WW2 30mm artillery projectile to his house, the bomb accidentally detonated killing him and his partner.

While on one side the deaths can directly be accounted to imprudence and underestimation of risks, to the other side it must be argued that the bomb did what actually was intended for: killing people.

I'm interested in knowing how experienced historians would debate over this.
