Torah and Taharah

Does the learning of Torah (just learning - even if it's Zevachim and Keilim) make one a better person/mentsch? If not, then our question is how can we teach morals to these intellectuals.

If one has yiras shamayim then learning Torah will further purify your soul. However, if one lacks a fear of God and does not work on one's midos nor actively attempt to fix one's behavioral and attitudinal problems, then Torah cannot serve to purify. Such a person is like one who immerses in a mikvah while holding an (impure) insect in his hand (tovel ve-sheretz be-yado - see how much more elegant Hebrew is than English).
