English is a tricky language. But that aside, it's not a good idea to expect constant 1:1 correlations between any kinds of languages.
"Till och med" means 1) up to and including or 2) that something exceeds the expected.
"Ens" means "at all", used here as an antithesis to "till och med". Ens means something is not even done, although one could have expected it.
