这样来看的话，地球上的所有生命都欠甲醛一个大大的人情啊，如果没有这个现在看来及其致命的有毒物质，也许地球上就不会有我们存在了。

杀了他？不，死亡是赦免，是解脱；死亡是送人情。难道我还欠他的人情不成？你连一根头发也不能伤他。

Kill him? No! Death is release, emancipation; death is a favor. Do I owe him favors? You must not hurt a hair of his head.

我还清了你欠那个组织的钱，我的人情你可欠大了！

I paid back the money you owed the organization; you owe me big!
