They know about goblins roaming the area, they don't know about how big the cult is, or the leaders.
They would if Aradin's group escaped and managed to tell the others. You know... After he made a distraction for them.
And even if he frees himself and waits until you leave with Minthara and teh forces, it is still a stupid plan. He could have been killed beforehand. He is entirely relying on Tav to free him or thin out the forces however.
Better than sitting in the Grove doing nothing while waiting for the Goblins to come and massacre everyone.
Also, he's not relying on Tav to free him or thin the forces out. The goblins would naturally thin themselves out as they either found the Grove and started an attack, or found some other place to raid.
To say nothing about, yes, he comes into action when Tav frees him. Doesn't mean he's not working on a plan to do something himself (Sure, whatever he does come up with fails if we account for sequence breaking by going to Mountain Pass early but that doesn't mean he was completely reliant on Tav)
I get, that you like the character
I actually don't. I hate the character.
But his situation regarding the goblins is not proof that he's some sort of imbecile.
1. I did not say , he is an imbecile, I said, he isn't very comptent.
2. Aradin can just leave again, which is pretty likely when he and Zevlor fight each other.
3. The goblins can thin themselves out by ... finding the grove? Wasn't that according to you the thing, oh so wise Halsin wanted to prevent?
You can look at it howevery you want, it doesn't make sense. I can get that he had an 'Oh shit' moment, got caught and waited until he found some intel and then vamoos. But just sitting there until he dies (if Tav does nothing and just goes to the mountain path) is just not a good plan. It might be a plan, but I don't have a lot of faith in it. Especially since those goblins eat everything and might look for the bear, if they get hungry again.
Why is it so important, that Halsin doesn't look incompetent in this caseP There is no evidence, that he planned to get caught or even did that to help Aradin and the rest. They all said, they lost sight of Halsin and just fled, when they realised, there are too many goblins. None of them said, that Halsin helped them flee, just that he charged and ran. So it is not clear, if he even tried to help them or make a run for the Selunite post.
