So if I dec some one to get what seems to be a dead corp dead stick pos out, and then they run to Dec shield it is my fault?

I do agrree nemesis of Buzz lightyear accomplished his goal of getting mutual fixed.
His new find may or may not work is now starting to push it.
Given that as he can not talk about it, but from the time line it seems he explicity sought it out rather than going and finding it to be a natural part of the game.
Sort of like how I can take down a pos without a personal war dec.
Not that it works anymore due to the change in flags.
Or does it, hmm need to go and test.

Point there, true.
Let's assume after a wardec declared on them, finding the agressors 1-man-corp OGB, they dec that? Agression, or evening the play field?
How about if carebears wardec notorious canflippers/ninjasalvagers aiming at them when only a few are online? Agression or self-defence?

Sometimes a war started before the dec, ignoring that is... ignorance.

Then again, it can get to kindergarten levels really fast:
"I did it because he did this" - "I only did this because he did that" - "That I did because this one time he..."

So wait no war dec= no conflict as defined in the EULA (ignore emergent gameplay here)
Thus what ever led to the need for war would go unpunished.
Given that none of these defending corps have attempted to do things on their own, I would say they are using an exploit to gain an advantage now.
If you were to tell me that the decced corp set it to mutual and then signed on all of nullsec through copious usage of alcahol and cash, I would say hazards of the game.
But now that the corp is running away from the fight and then being told its not their fault and the other group was bullying issues arise.
And saying well its a bugged system so you shouldnt use it is an example of ill thought (similar to blaming the Austrailian DJs for the nurses death when the international media declared her persona and everything else)
Given that dec sheild was explicitly created to remove any threat to defenders by decoupling consequences of war from the actions precipitating I would say that it definitely should be shutdown now that its stated goal is over.
Further continuance of its existence risks mission creep as it attempts to find ever more bizarre reasons to justify itself.

The stated goal was to get mutual wars to not be a flip switch walk off thing, and about wars carrying.
Both of those have been fixed.
He has a possible third one that is related but doesnt talk about it since he is in dialogue with CCP on it until the 12th.
So if those clear any further existence is as mentioned mission creep.

Spoken like a true troll of attention that you are.

Ooh good point.
That might just be her main.

Also what will you do now that people no longer require proxies to deal with Dec Shield?
Just dec all the corps anyways?
