I agree with Munsu that in retrospect he hasn't been as much of a burden as he seems, but this is due to mere luck and coincidence.

I think what Kraco is trying to point out is that the main character is so weak that it makes it really hard to root for him, and really easy to hate his interfering nature when he does not think ahead nor has the strength to back it up.

I personally slightly dislike him just because of the voice.
