It's fine to use intuition, but it's extremely important to be able to reflect and recognize on its shortcomings, which is that you may be inadvertently layering your own subjectivity on what you think is objective. In this case your outburst is not valid.

Is forcing yourself on another person immoral? Yes. Is intentionally manipulating someone's relationship for personal gain immoral? Yes. Are two people recognizing they would be happier together, and leaving a previous relationship immoral? That doesn't seem wrong.

You are the one coloring this scenario as "stealing". There is no information here about who these people are, what their relationships are like. You are projecting onto this situation and constructing this strawman, and in turn moralizing about the strawman. That isn't reality.

All morality is subjective and thus so are my views. My views are still valid according to majority consensus DESPITE being subjective. Intuition has shortcomings but not when it comes to something obvious.

>Is forcing yourself on another person immoral? Yes. Is intentionally manipulating someone's relationship for personal gain immoral? Yes. Are two people recognizing they would be happier together, and leaving a previous relationship immoral? That doesn't seem wrong.

The last statement isn't immoral, while the first two are. However I am not addressing any of those things. What I am addressing is this: Allowing yourself to engage in a relationship with and/or develop feelings for your best friends, girlfriend. This is wrong under all counts.

>You are the one coloring this scenario as "stealing". There is no information here about who these people are, what their relationships are like. You are projecting onto this situation and constructing this strawman, and in turn moralizing about the strawman. That isn't reality.

Perhaps "stealing" is an inappropriate word as we are talking about things that are fundamentally impossible to steal. Betrayal is a better word and it is exactly the scenario the OP describes.

If we asked said betrayed founder whether or not he thinks it's betrayal. His answer will be yes. Then if we ask the majority for consensus. The answer will be yes, again.

The problem is that this is your subjective interpretation of what YOU think the consensus is. This is what you think other people think is wrong. Why should someone on this board believe that your conclusions about the consensus are accurate, reliable, or valid? No one is interested in sorting that out. In contrast, the best information to offer here is experience, AKA a data point. Fundamentally your input here is suboptimal.

It's also really clear that what the consensus may be here would vary a ton by the actual situation: 1. Was the original relationship happy? Would the consensus be against this if it were an abusive relationship? 2. Was it just a casual girlfriend, or were they engaged? 3. Was the OP intentionally trying to seduce the girl, or did it just happen that they recognized it was a better pairing?

The reality is the consensus WILL differ based on the situation. There are a ton of shades here, but you fixated on the idea of "betrayal", as if all things with this pattern were uniformly bad. That's clearly not true, and there is simply not enough data for you to overfit and then moralize.
