UlagaNayagan KAMALHAASAN in ||"UthamaVillan"|| Directed by Ramesh Aravind

What is the purpose of showing him maintaining a clandestine relationship with Arpana till the very end even after all his repentance. I felt there was no necessity of that display at that point.

It clearly shows he is not perfect like uttaman. Plus, it shows in many ways that his true love is Arpana and not his wife. From another perspective, it shows reality as it happens in the real world. Haven't you heard of extra marital affairs including perhaps some aspects of Kamal's real life?
