Can harm come from submitting to others
Though the starting post is old, let me respond. Perhaps you are still interested.
If I understand you correctly -- you are asking ◇(S ⊃ E)? -- then the simple direct answer is "Yes." We could for example say that there have been cases where someone submitted (willingly or unwillingly) to someone else and some evil resulted therefrom. So the proposition -- ◇(S ⊃ E) -- is true.
Is there a next question having something to do with submitting to God or Christ or something like that? Just wondering.
