Question for libs

If I have a loved one living with me that isn't self-sufficient and I lose my job and will have to struggle to continue to meet their and my needs, do you think it is okay for me have someone come in and end it for them? Also, suppose it's a person that weighs over 600 lbs, is it okay to rip off limbs and other body parts while they are still alive so I can get them out through the door?
