Section 84 IPC - Mental Capacity vs Culpable Homicide

Can you believe this question for CLAT PG/AILET PG? Alright, let's dive in!

Section 84 IPC deals with the plea of insanity, stating that nothing is an offense which is done by a person who, at the time of doing it, by reason of unsoundness of mind, is incapable of knowing the nature of the act, or that he is doing what is either wrong or contrary to law.

Question: A kills a child under the misapprehension that it was a snake, due to which he suffered temporary schizophrenia. Does Section 84 IPC absolve A from criminal liability under Section 302 IPC? Option 1: YES, because the defense of insanity should be accepted as A did not understand the consequences of his actions. Option 2: NO, because the fact that A's insanity was short-term doesn't negate his voluntary act of killing the child.
