His fear is what makes Stark stronger than Eisen. Demons specialize in manipulating their enemies to have them let down their guard because that's the type of inhumane predators they are. Humans get overconfident, and then they get killed or worse (like what Aura does) because demons play weak when they can, either to give them a new opening or because they think it is entertaining to toy with their prey.
Stark has confidence issues, but his fear is what will keep him alive because he will never get overconfident. Eisen was the same way.
The series is pretty consistent in the point that to successfully hunt demons as Frieren has for a millennium, you are either go full force on them right away like she does, or you goad them into trying to toy with you first, like Fern does.
Frieren has been teaching Fern to be underestimated for being a human, or for Fern to imitate her to make them furious. Eisen's strategy for his protege is simply keep getting back up and smash them. Hah.
Linie kept thinking that Stark was weak, or at best "strong for a human," which is what warriors need to kill demons. Aura has the same weakness when someone has strong willpower, but she found a gruesome way around that.
edit:
Also, Stark has been in legitimately like...four real battles. He ran off during training, stared down a dragon, then trained again for another two years.
We learned that Frieren has been doing her lazy thing again and making Fern do all the fighting since they started traveling, but mostly so Fern can excel and have experience to make up what she lacks in capacity.
