Some cats may want to kill you or hurt you but not all cats will want to kill or hurt you.
I have 2 wonderful cats that seem to love me and I would not think they would want to kill me or harm me.
If my cats wanted to kill or harm me I'm sure they would've done so already and even when I'm asleep.
My two cats sleep with me in my bed so they would have a good chance to kill me or injure me.
If you harm a cat then they might want to kill you or maybe a larger cat such as a tiger or lion would more want to kill you.
But small cats that are pets are usually pretty friendly and loving and do not want to kill or harm you in any way.
