He "remained" just as ignorant as the rest of us. You're still implying that if he had done more research, he could have found out that those seeds, in his condition, could kill him. He could not have.
Yes, he took a risk. But I don't think it's a significantly different risk from other risky activities young men in their early 20s do, ranging from unusual sports to the military.
He was starving even without the seeds (it was only because he was starving already that the seeds did him in) because he did not actually know how to survive in the wild. Neither do I, but I am smart enough to know that and not attempt living in the wild.
