不要对人性丧失信心。人性是一片海洋，如果其中有几滴脏水，海洋也不会变脏。

You must not lose faith in humanity. Humanity is an ocean; If a few drops of the ocean are dirty, the ocean does not become dirty.

多年的内战已经使我们大家丧失了人性。

The years of civil war have dehumanized all of us.

《柯林斯英汉双解大词典》

人类对时间的执念——对其的节省、玩弄、浪费、丧失及掌控——似乎是人性的一部分，人类存在了多久，执念就存在了多久。

An obsession with time, saving, gaming, wasting, losing and mastering it, seems to have been a part of humanity for as long as humans have existed.
