Father and son

I came across a Persian poet titled Rostam and Sohrab, from the epic Shahnameh by Persion poet Ferdowsi.
Pride can never undo love between a father (Rostam) and a son (Sohrab). Rostam killed Sohrab and later found out that he was actually his son. Sohrab's last words:-

If thou art indeed my father, then hast thou stained thy sword in the life-blood of thy son. And thou didst it of thine obstinacy. For I sought to turn thee unto love, and I implored of thee thy name, for I thought to behold in thee the tokens recounted of my mother. But I appealed unto thy heart in vain, and now is the time gone for meeting...

 Never let pride blinded us all.
