Compare the characters of the astrologer and Guru Nayak in "An Astrologer's Day"?

This is a difficult comparison. Surely being left for dead
significantly alters a person's inner character. This raises the question: Is what we
see of Guru Nayak his true nature or the manifestation of a traumtized nature?

What we do know is that Guru nayak's behavior is beligerent and
antagonistic to a person whom he believes to be an innocent by-stander. When he first
encounters the astrologer, he shaoves his palm toward him with a short
insult:

whereupon the [Guru] thrust his palm under his
nose, saying: "You call yourself an
astrologer?"

The Guru follows
this up by actually challenging and betting with the astrologer, insisting on the
challenge, even when the astrologer tries to opt out in response to Guru Nayak's great
antagonism.

We also know that the only reason he leaves his home
village periodically is on a murderous quest of vengence. Whereas the astrologer
attempted murder in his uncontrollable youth, in the heat of drunken argument, and over
gambling debts, Guru Nyak wishes to murder according to premeditated, persistent
searching and planning.

The final thing we know is that, after the
astrologer astounds the Guru by telling him the whole dramatic event of his past brush
with death, Guru Nyak leaves without fulfilling the terms of the challenge: he leaves
only twelve and a half annas when he promised a whole rupee.

After
their encounter, the astrologer's prevailiong thought is that he does not have blood on
his hands:

a
great load is gone from me today ... I thought I had the blood of a man on my hands all
these years. That was the reason I ran away from home ... . He is
alive.

Guru Nyaks's
prevailing thought at their parting was gratification at the report that his foe "was
crushed under a lorry [truck]."

Both men have pursued employment and
have done well, in the Guru's case--well enough to promise rupees and smoke cheroots--or
only just well enough: "I can buy some jaggers and coconut tomorrow. The child has been
asking for sweets for so many days ...." But not both have attempted to purify their
character traits so that the violence of their youth doesn't govern their lives again:
it is only the astrologer who has attempted to lay his  "silly" youth
aside:

"He is
alive."
She gasped. ":You tried to kill!":
"Yes, in our village,
when I was a silly youngster, We drank, gambled, and quarrelled badly one day--but why
think of it now?"
