Why did God Krishna enjoy the scoldings of Shishupaala while He became angry with Duryodhana for the same scoldings?

[A question by Shri Kishore Ram]

Swami replied:- The two gatekeepers of God Narayana were cursed by the Sages for their misbehavior. Then, God Narayana asked the gatekeepers whether they will come back in three births as enemies or in seven births as devotees. The gatekeepers preferred the first option because they can reach God quickly. They have to scold God Vishnu as enemies as per this agreement. Hence, Shishupaala scolded God Vishnu. Such background is not present with Duryodhana and he scolded God Vishnu really as a real enemy. Hence, God Krishna made Shishupaala to merge with Him after his death. Since Duryodhana was a real enemy, God Krishna became angry and showed the threatening cosmic vision (Vishwaruupam).
