What's your thoughts about abortion or human euthanasia?

I have a family member riddled with cancer and she had her lawyer applying for euthanasia and it was declaimed at great cost because it’s on grounds against human rights. She have have chosen to die. Is it not her right to do so?
I find it strange that abortion is acceptable to kill a baby.
But when a human suffering from cancer and asked to be euthanized it’s murder.
We euthanize our pets when they are suffering so why won’t the law allow us to do it with humans?
