Lord of the Empty Seat

She had to learn about the amulet somehow, and was more than willing to dismiss the danger is possessed, then she knew about the risks and thought she was strong enough to handle it (if she's overly self-confident enough to believe she can take credit for beating an ursa, then she's overconfident enough to believe she can surpass a corrupted amulet), again, her ego got her into trouble.There's the difference between harassing villagers with corrupt Magic and zipping someone's mouth shut for harassing them. One (Trixie) is more drastic than the other.Also, there's the fact that the reason she got the amulet in the first place was simply because she wanted revenge for Twilight for one-upping her… despite the fact that Twilight saved her life, so we can write ungratefulness and disappropriate retribution to that list as well (plus even after she lost the amulet she tried to cast a spell that make Rainbow Dash writhe in agony, so even then she wanted to assault someone for unjust reasons).So yes, the bill goes to her.Now we're done. Unless you want more reasons as to why Trixie's more in the wrong than Twilight, I suggest you zip it.
