Well a Muggle murderer can't create a horcrux as the second part is to cast a spell- I'm not certain if it would tear their soul- but the soul fragment at least wouldn't be separated from the rest of the soul and tied to an object.

Thankyou I was looking this answer for years

He killed 7 people and put a horcrux into the 7 things

Fine

Hi and howz you?

That's nice

June 19

Almost two months

There's a very detailed explanation, lemme write it out, it isn't mine it's from night-vale-secret police on tumblr

When I used to think about Voldemort's horcruxes I imagined a soul divided in equal portions residing in the different horcruxes and Voldemort himself. I realized this can't be true in the half blood prince slug horn describes making a horcrux as splitting one's soul in 2. This means that when riddle made his diary into a horcrux he split his soul in half and physically removed one half from his body and placed it in the diary. This means he only had half his soul left when he made his next horcrux, marvolo's ring. This half would have been split in half leaving only a quarter in Voldemort's body. This goes on and on the amount of soul remaining in Voldemort halving each time he makes a horcrux until he had only 1/128 or 0.78125% left in his body.

There's a pie chart and its color coded as dark blue, red, green,purple, teal, orange, light blue, and light pink. Half of the entire circle is dark blue for the diary. Then 1/4 of the circle is red for the ring. Next 1/6 of the circle is green for the locket. Then 1/8 of the circle is purple for the cup. Next 1/10 of the circle is teal for the diadem. Then 1/12 of the circle is orange for Harry. Next, 1/14 of the circle is light blue for Nagini. Lastly 1/16 of the circle is light pink for Voldemort himself.

It's weird bc basically Harry had more Voldemort in him than Voldemort himself did.

Hope this helped
