"It was an accident I swear It wasn´t meant for him!"

"And if I turn it to me, if I even it out, can I still get in or will they send me to hell?"

This is the ending of their song "King park". I dont know why but I can´t get this part out of my head. The person in the text thinks that he can "even it out" by taking his own life because he killed a kid. He think that all the sins will be forgiven, I have so many thoughts around this text I think its really intresting.
What to you think about this text, will he be forgiven cuz he took his own life becouse he killed a kid?
