Do good (agaqopoihte). Third-class condition, ean and present subjunctive. This verb not in old Greek, but in LXX.
Even sinners (kai oi amartwloi). Even the sinners, the article distinguishing the class. Matthew 5:46 has "even the publicans" and 5:47 "even the Gentiles." That completes the list of the outcasts for "sinners" includes "harlots" and all the rest.
