Mental Aberration and Insanity in CrPC

Picture this: Bollywood's most famous villain, Aap ki adalat me hamesha khade rahte hain, lekin courtroom mein kya hoga. Unka statement "Maine apni zindagi ko kho diya" kyu valid hai? CrPC Sec 84 kehte hain ki jab koi mental health ka samasya hai, or vah kisi bhi baat ko valid rakh sakta hai, to bas ek baat, vah aisa karega bhi, jo sahi nahi hai. Yeh kya hai? Yeh kya hota hai jab ek vyakti ko apni mental health ki samasya ke karan woh aisi cheezein karta hai jo sahi nahi hai.
