On numerous occasions members of the Hand pronounce these arc words, which seem to be their motto. This feels out of character for me, because from what was shown of their character in the Defenders, they appear to be self-centered, if not egotistical, their main concern being prolonging their own life. Them serving some different, 'higher' cause puzzles me.
Is that meant to be taken ironically, since they are 'serving' for the sake their own lives? Or is there a possibility that their organization has got a different purpose?
