Sure, but guilt and ethics don't require the concept of sin. He can feel whatever he feels about the situation. But us, as a society, could not have asked for a better outcome to this situation. The danger, imo, is more in mythologizing this kind of action and removing the context. But on a personal level, the two actions aren't comparable. This leveling effect of modern christianity is just vapid. How do we, as a society, benefit from that?
But, more to the point, how does this compare to trans issues? I'm not really a biblical expert but I'm pretty sure Jesus didn't say anything about dick chopping and drugging children, it's more an ethical issue and reflects on the consistency of values/beliefs rather than the acceptability of any particular action. And for sure isn't comparable to the church shooting thing, on any level.
