Undertale: Chara's End

(I use Them, their, they here to refer to both chara and frisk)
(the bold ones are chara)

This is how i imagine when Frisk confronts Chara

Frisk tries to save chara
At first chara fights frisk mercilessly, doing all sorts of tricks 
Then everyone, every monster from the underground arrives to help frisk. 
Chara then taunts them, telling them all about the stuffs they did, telling them how fun it was
With everyone attacking, Chara’s HP went down to 1 

Then Frisk, just like when they fought Asriel, went to CHara's memories 

Frisk hugs chara, telling them to stop and that they already understands

Just when CHara was about to give up, they stabs Them-self and says

"Congratulations on defeating the demon.....”
Chara knows that there’s no helping them, maybe Frisk forgives them but that just because it’s their personality.
The others, the monsters surely still despise chara

.....also
If Frisk or anyone was able to Kill chara, who is the filled with EXP and LOVE
then it will surely be transferred to that person.

Since there’s no other way around, killing their-self is the last option for chara.

Is it for redemption? They do not know.... 

Frisk starts to cry
“hey why the hell are you crying?...you are too kind frisk..."
"we both know how scary the world above"
"but since you have those guys"
"ha ha..."
"I live in the world where it's kill or be killed....I have no place in your world"
".....go...leave me....go to your HAPPY ENDING"

Frisk replies
"you are not demon....you are just a human child....like me"

Chara replies
"ahahahaha....you really are too kind....we all know that I don't deserve any kindness"   

Chara whisper to themselves: “This will be my third suicide, haha....This should be a world record” 

Chara's black soul shatters
