What irks me most about Gajeel is that he never apologized to Lucy for torturing her out of boredom.

If I was Makarov - or any FT member for that fact - I'd have made that a requirement for him joining Fairy Tail.

Okay, maybe not literally apologize, but he should do something to repay that debt.

He always struck me as someone who's unwilling to accept help for the sole reason of not wanting to owe anyone a favour and thus he should really repay his debt to Lucy (Levy's, Jet's and Droy's beating can be blamed at least partially on Jose, but Lucy's torture was entirely his own decision and even going against Jose's orders) even if she forgave him already.

But all that's still not making him wrose than Lisanna in my opinion.
