I hear you, torso, and I've honestly had some of the same feelings from time to time. In this case, since the OP asked whether some types of infidelity are worse than others, I think it makes sense to discuss whether the priorities and goals of the BS, in conjunction with the specific offense of the WS, influence that evaluation. What I'm not buying, and never have, is the argument that such decisions are typically based on principle and philosophy rather than emotion and practicality.
Take an example that removes infidelity from the discussion of justice. If a drunk driver kills someone I love, then honestly, I don't think I'll give a tinkers damn about self-esteem or philosophy. I'll want them to suffer. I'm not going to assign higher motivations to that. Nothing will bring my loved one back to me, so in the absence of restorative justice, I would want revenge.
Once I establish that as my motivation, then other factors might harden or soften it. Would I feel differently about the punishment if the kid in the driver's seat was the underage child of a long time family friend vs a fourth time offender operating the car with a suspended license? If my family member's injury was minor, would I be less eager to see the offender suffer, even though the action of getting behind the wheel while intoxicated was identical regardless of the outcome?
Would my view of abstract justice vary if the person I loved was the offender rather than the victim? If my kid ran me over, would I react the same way as I would if a stranger did it? Would my thirst to hurt them be partially slaked by compassion? What about my own self-interest, the consideration of how different my life would be if they were incarcerated instead of coming back home?
If, God forbid, I'm ever in those shoes, I don't believe that self esteem and justice are going to be the deciding factors in how I react. Shock, grief, rage, helplessness, exhaustion, despair, bargaining, and eventually, an evaluation of how I can best rebuild my life, and show up for other people who rely on me, are going to be my priorities.
I understand that it's simpler for some folks. They can cut ties without a backward glance. I've seen it done in my own family, in a scenario that's much closer to my hypothetical than it is to infidelity. But neither my spouse nor I wanted to do that, and our choice to work it out was not influenced by self esteem, abstract concepts of justice, or belief in an obligation to forgive. We just wanted the things we could salvage and rebuild in our marriage more than we wanted the benefits of breaking up. I don't believe that decision requires justification, and I rarely engage in discussions with people who do.
