Translation of "Imperfectly" in Japanese

Though imperfectly, he finished writing his manuscript.

曲がりなりにも彼は原稿を書き終えた。

You may as well not do it at all than do it imperfectly.

中途半端にやるくらいなら、やらない方がましだ。

I'd rather not have those written by people who only know their work imperfectly.

仕事を生半可に知っている人が書くことは、できれば避けたい。

One may as well not know a thing at all, as know it but imperfectly.

物事を中途半端に知っているより、全く知らない方がましだ。
