Who was right?

It was a serene evening. My mom was chatting up with my son and was naratting the Krishna - Sudama story to him, a version used in some places. She told him how Krishna
and Sudama were friends in Sandipani's Gurukul, that Krishna loved poha and how
Sudama stole a handful of poha from Krishna's plate while He was looking
away. She continued to narrate the story as to how Krishna went on to
become a king and Sudama a poor brahmin, unable to feed his 27 children.

Mom narrated, "So Sudama's wife suggested that he approach Krishna asking for help.
'How can I ask for help from my friend' asked Sudama. Sudama's wife
told, 'okay, do not ask him for help, just visit him and come back.'

'Okay', said Sudama. Sudama's wife packed some poha for Him and Sudama
set out to Krishna's palace. Once he reached the palace of Sri Krishna,
the dwarapaalaka (guard at the gate), did not allow Sudama inside. However Krishna saw
Sudama and came running to give a big-hug to his old friend. He took him
in and made him feel comfortable. Sudama stayed for a few days and told
Krishna that he wanted to go back to his home. So Krishna gave him
permission to leave.

But before Sudama left. Krishna noticed that he had a bag which he was
trying to hide. 'What is in that bag?', He asked. Sudama was embarrassed
to show the humble gift he had brought to give his friend. However, the
moment Krishna saw that it was poha, He took one handful of poha and had
it. When he reached out for the second, Rukmini stopped him
saying, 'one handful is enough'.

A disappointed Sudama left for home. And when he reached home, surprise
was awaiting him. In the place where his humble stood, there was a
palace. In the place of 27 poor, malnourished, wailing children, he
found healthy children playing away merrily. He found his wife wearing
expensive clothes in place of her usual tattered clothes. So actually
what happened was, God had held back all the riches which Sudama was
supposed to get, as he stole His poha. So when Krishna got back the one
handful of poha, which Sudama stole in his childhood, all the riches
which he was deprived of, have been given back to him.

So the moral of the story is that we should not take other's belongings.
If we do, then we will not get what we should rightfully get."

My son pondered for a while, and said, "Krishna is a bad boy".

My mom was shocked. She asked, "Why?"

"See. Sudama is Krishna's friend and is from a poor family. He would like
to taste a little more of poha which he will not get at his home. Anyway
Krishna is a rich person and can get how much ever poha he wants. So as
a good friend he should have shared his poha with Sudama. Even if Sudama
took it from Krishna's plate, how will taking from a friend's plate
be stealing? So, it is Krishna who is wrong. We should not punish friends. We should help them."
