Am I evil person

I know this post will sound stupid but ever since my divorce I have been living with my grandfather. this is  most time we ever spent togther . main reason why is because he got remarried The year I was born .turns out is now wife who is a demon left him she is the main reason why none of his grandchildren spent any time with him growing up . she made sure we wernt a big part of his life .   my grand father is a sever heart patient. He works in construction and after his first stent he was back at work while his wife did nothing but give him agervation . I listen to his story’s about her grand children how he took care of them ….I don’t want to be mean I know these kids had a way more harder life then I can in any way imagain . but I pretty sure there out to kill him honstly there this little boy my grandfather adopted his wife’s grandchild . I can understand why my grandfather grew attched to this kid he lost a son 23 years ok so replaced a missing part .

but the boy’s biological father just entered and my grand father is going but there gonna give him an heaet attack and kill him they want him tooo.

The reason I’m upset is he has given up on life he want to die he’s old no good ….but he talks about saying strong for this kid …not me my siblings or his 7 other grand kids . he would rather die when I’m with him then with this kid . 

I listen stories about him and his fake grandchildren ….I am 21 years old this year was the first 4th of July we spent together two weeks ago was the first movie we saw together.

He asked why we didn’t hate my grandfather Wifes on my mom’s side .  well she didn’t keep him from us she tried to have a relation ship with the kids. We didn’t like her she didn’t like us but we faked it for his sake . the woman married to my grandfather on my dads side they were together for 20 years she never tired to fake it .

Idk what i am even rambling on about sorry .
