Merciful killing

I have no idea with merciful killing till such time that my grandmother rush into the hospital because she cant breath. I thought everything will be going fine and she'll be recover soon but i was wrong😂😂😂😂. The doctor told us that even though she had survive the hearth attack by that moment, still it is useless, she will live yes, but since the attack was heavy, she will live like a sleeping beauty or like unfresh vegetable. Besides she was already 81 years old by that time so the doctor told us to let her rest. I just thought that the rest he was saying was to let our grandma to sleep. But i was shock when the nurse enter the room then remove all the machine connected to my grandmother then they just wait her to lose her breath. For them, my grandmother need to rest, rest in peace. I Miss my loving grandma. And i hope that she was really in peace right now 😢😢😢😢
