IMO if you KNOW something/ someone is evil and do nothing to stop it, that makes you just as evil as the person commiting the evil. So the blood is on Elrond's hands as well.
Except Isildur didn't actually do anything overtly evil at that point. He was killed and the Ring lost for millennia. Sauron was discorporeal for centuries on end and unable to work his will. Is that truly evil?
In any event, the point is that at that point in time, there was
nothing Elrond could do that would not have corrputed his own soul and caused him to lust for the Ring and set himself up as the new Dark Lord (Elrond is certainly powerful enough to do so). His choices were (a) convince Isildur to voluntarily give up the Ring, (b) failing that, let Isildur go and hope that the job can be finished later, or (c) try to take the Ring from Isildur and either become corrupted himself or drive Isildur to further corruption at which point either he or Isildur would st themselves up as the new Dark Lord.
Elrond was unable to accomplish the convincing option, and chose the option of
hope. Staying uncorrupted prevented the immediate erection of a new Dark Lord and allowed Elrond to assist in the events that later resulted in the Ring's destruction.
Say you had a chance to destroy someone evil, and you do not, then that person goes out and commits unspeakible acts. But your soul is pure becuase you did not try to stop it? I don't think it works that way. You did nothing, that makes you partly responsable.
This assumes that the "something" you could have done
would have been effective. In Tolkien's world, when dealing with the Ring, the course you advocate would have destroyed Elrond. Basically, you would have had Elrond make the same mistake Isildur made, and have two powerful lords fighting over the Ring, becoming corrupted evil beings almost immediately. As I said before, Elrond chose to stay his hand rather than compound Isildur's error and prevented a war that would have only resulted in a new Dark Lord rising to replace Sauron with no one left to oppose the new evil. You would have caused this very thing with your rash and violent plan, which is why Elrond was counted as one of the wise, and you probably would not have been.
