No Respect For Inlaws

I know that our Indian parents have always taught us to respect elders and I did that for almost 15 years .
Now I have come to a point of adulthood in my life where I have become too mature to just respect someone based on age. Of course , when I meet someone who is old age : I will always have a respect of age for them and I’m always nice to them
But with my In-laws , I have no respect left for them
I mean seriously , my words may cause a spark but I dnt respect my in-laws at all . I rather look down upon them
The reason being : as a person ( not in-laws) I find them cheap, manipulative , liar , self centered and always using situations for their benefits . I’m not just judging them on their behavior with me but to others as well. I’m sure the relatives in India see how cunning my mil is with words and always praising herself for small little things which she may do and when it comes the time for big things or actual doings : she stays mum and plays the old age card or health card . If I see , I’m sure the other relatives see that too but they being relatives, wnt point it to her on her face but I’m sure they talk behind her back

She is manipulative and a liar and my Fil stays quiet knowing that she’s lying . Hence I dnt have any respect left for both of them
Is that normal ? I dnt want to be that typical Indian Dil who should be respecting them all the time no matter what.. I’m done with all that and I feel that I’m too I dependent and self made and if I choose my friends and people I want to spend time with , I should not be dragged with negative folks like these .
I sometimes literally look down upon them . I never say anything like that to my husband or anyone but inside I have been feeling guilty as well . One side of me tells me that respect is something that a person gains with their behavior and in 15 years you cannot just force someone to respect someone . If they were nice as being normal parents , they would still have some respect from me but I see that they even manipulated their son and try to use him as much as they can and have double standards with him as well . Hence I have zero respect for them
Tell me
1. Is that an ok feeling?
2. My husband wants to move them sometime and how will I live with people I dnt respect ? Rather I actually look down upon them as manipulative liars and hungry money snatchers . I dnt trust even a single word that comes out of their mouth and I alway doubt them for playing me and husband ( husband never sees that and gets too emotional )
