Adultry affair of my uncle

Sir, I am from Visakhapatnam, 21 yrs old male. My uncle 40 yrs old (elder brother of my mother) has married 14 years ago and now had 2 daughters and staying at my aunty's house since marriage. The only person i love most in this world is my uncle, he is only educated in my village, no drinking, no smoking, everybody respects him. I have got to know in 2014, that he is having affair with an unmarried PHYSICALLY HANDICAPPED lady (23 yrs old). After some investigation, i got photos (close together), SMS & call history (romantic chat). And he spending 3-5 hrs daily at her house, later coming back to the home. My aunt don't know anything. One day they both traveled to mumbai, when i know this ,i got into depression and left my home for 5 days and informed to my mother, my uncle's father. I want to break that relation without knowing to my aunty. if i approach police station, what kind of action is taken,, i am thinking like this, if i approach court, they will take action (fine or prison) and then giving counseling and make my aunt & uncle together as previous. How can i make happen like this. If doesn't happen like this, the most good solution with me is KILLING that handicapped lady and get into prison. Then the result is My uncle & aunt will be together and moreover stays at my grandfather's house (Makes my grandfather, grandmother, aunt, uncle, my mother, my step mother happy). If any god's grace on me, i will be out of prison after 6-8 years or i will be in prison for lifetime.. i have no other option.. if any please please please help me...
