BASE, LOW, VILE mean deserving of contempt because of the absence of higher values.

LOW may connote crafty cunning, vulgarity, or immorality and regularly implies an outraging of one's sense of decency or propriety.

e.g. refused to listen to such low talk

VILE, the strongest of these words, tends to suggest disgusting depravity or filth.

e.g. a vile remark

｟文｠ 〈行為などが〉(道徳的に)恥ずべき, さもしい, 卑劣な, 卑しい

basely |ˈbāslē| adverb

late Middle English: from Old French bas, from medieval Latin bassus ‘short’ (found in classical Latin as a cognomen). Early senses included ‘low, short’ and ‘of inferior quality’; from the latter arose a sense ‘low in the social scale’, and hence (mid 16th century) ‘reprehensibly cowardly, selfish, or mean’.
