[ it's hard not to have sympathy for well-meant intentions, especially when Aventurine is no longer bound by his job to succeed. Although he doesn't want to, he can't help but be tempted to admit a man that sacrificed everything for his sister's (and the rest of Penacony's) happiness while throwing away his own is a bit worthy to be envious of. If Aventurine could have his sister alive with him, he doesn't doubt he would burn down the world for her, as well. And he would be also very tempted to keep her safe in a cage from the dangers of the sins of men.

Because Aventurine is so very well aware of how terrible self-serving and selfish he is. ]
