I think Medaka Box is what you're looking for.

Noblesse

________________

There's actually a lot of protagonists like this outside of the mainstream action shounens. Try the Antihero tag.

Now, for actual recommendations...
Break Blade
Franken Fran
Gunka no Baltzar
Historie
Immortal Hounds
Jackals
Jiraishin
Mugen no Juunin
Shin Angyo Onshi
Shut Hell
Wolfsmund
Young Gun Carnaval

Not really sure what you wanted (since your "winning with something other than the power of friendship" request is really broad), so your mileage may vary with these.

Shoukoku no Altair - although the protagonist isnt cold and is kind of naive at times he still seems like the kind your looking for. he considers everything in his battles and that includes sacrifices that have to be made.

Kuroshitsuji -MC in this one is definitely not the to say he won because of friendship. although he has a nice side, when it comes down to it he will do anything to get what needs to be done
