As for the DCEU Johnatan Kent, there is absolutely nothing wrong with his attitude towards Clark's powers in general, I just don't think it's the kind of attitude that the character should have. Through pretty much the entire history of the character he's always been Clark's biggest supporter and the one the people who encouraged Clark, so to see a version of the character go so completely against that feels wrong.
DCEU Pa Kent is the worst Pa Kent ever, no doubt, but I do find it interesting in an Elseworlds sort of way. We're used to stories where Clark gets his moral code from Jonathan and Martha, so it's interesting to see a version where Clark still becomes an intrinsically good and heroic person despite Jonathan. (Although then BvS rewrote history by having Clark say that Superman was his father's dream, instead of Clark's direct repudiation of his father's terrible advice.)
