IPC 302: Kya Logic Hai Yeh?

Meri duniya mein, Section 302 IPC ka Matlab kya hai? Murder ke case mein, kya jo bhi karke maut hoti hai, tabhi Section 302 lagta hai? Lekin, koi baat, yeh nahi hoga. Mera dost ne bola, agar koi murder karke police ke saamne aaya, aur usne confession kardi, toh woh Section 302 ka victim hoga. Lekin agar usne murder karke bhag gaya, aur police usse pakadne nahin paya, toh Section 302 kahan? Acha kya hoga, woh ek different section ka masla hogi? Abhi tak, meri confusion nahi chuki. Kya meri understanding galat hai?
