I'm not so sure about that. She took him deeper than he was ready to descend and then used the whatever bait crystal to summon multiple high level monsters, which promptly surrounded him. Like I said before, it's obvious her intention was to cover all the tracks by making him a dime a dozen adventurer, who got killed in the dungeon. Happens all the time, can't be helped, so nobody would suspect her or come after her. If Bell had survived, he would have naturally hunted her down, which can't be a part of anybody's plan. She didn't exactly pick his pocket this time.
I might have forgiven her if she was a child, but those breasts don't belong to a child. But whatever. Bell 'Jesus' Cranel forgave her, so that's all.
