You have some perplexing examples there.
I can agree eating something based on a desire to eat it and neglecting the thought of not eating it leading to being overweight.
When people lie, they usually do it to avoid negative consequences they foresee. Are emotions capable of predicting the future? I would say no, logic is, and it’s typically logic that determines lying to be the best way to avoid it. There may be emotional acting at play, but not emotional thinking, unless your lie gets found out.
What makes a relationship bad? Typically experiencing bad emotions such as anger, frustration, pain, and stress. These emotions would presumably push someone to leave, but if they talk themself into staying that’s logic keeping them in that situation, poor logic as it may be.
There is no interesting conversation to be had regarding religion here.
How is something being hard an emotional response? Sorry, since it hasn’t happened yet, how is calculating that something will be hard emotional?
I don’t understand how understanding another person’s emotional state is a moral response or how subjectivity is arbitrary, or how either could indicate that emotions are wrong or not useful.
You mention faulty logic being used to justify initial emotional responses but if a person is acting on their initial response I would say they’re not applying logic in the first place, though I do agree that logic is fallible and no person is capable of perfect reasoning.
Ultimately, and based on your first paragraphs you may agree to some extent, emotions aren’t something to be controlled or repressed, they are something to be acknowledged and understood, and often in that understanding the best response can be found.
When you want to eat, is it a feeling of genuine hunger or boredom? If the former, you likely won’t get overweight if you eat, but if the latter what would be leading you to be bored and is there something that could make you less bored? If you just really like food because it makes you feel comfortable you could exercise frequently to enable that emotion in a healthy way.
When a person determines lying to be the best option to avoid trouble, and they feel guilty, would that negative feeling push them to act in a way to better avoid thinking they need to lie going forward? If they don’t feel guilt, would you say there is something emotionally wrong with them?
If a person is in a bad relationship, would negative feelings not be what tips them off that something is wrong and prompt them to understand why they feel that way, giving them the understanding to express what they need to end that feeling?
