There are two types of people who do evil. Those who want to do evil, and those who cannot help it. The Chovos Halvavos is loaded with proofs of how the main thing is what you want to do, & Aveiros: גג ַוֹשׁב ַ done unintentionally are a different world than: יד ַז ַמ ַין intentional ones.
Do’eg HaEdomi and Shaul HaMelech were both involved in destroying Nov Ir HaCohanim. Despite this, Dovid is constantly in awe and respect of Shaul, and he curses Do’eg so he should die young and lose his Olam HaBah. (Gemara). Shaul remains one of the great: יכ ַס ַנ ַים princes of Klal Yisroel (Gemara), and Klal Yisroel was punished years later because he wasn’t: פ ַס ַנ ַדַ כ ַהכַָלַָה ַ eulogized properly. (Gemara).
The Gemara mentions that one of the great keys in keeping the entire Torah, is: לֹאַרָ ג לַַ ע לַ ל שׁוֹנוַַֹתהליםַ טוַ ג not saying Sheker. The Gemara gives Yaakov as an example, and the Rivan (printed on the page instead of Rashi) explains that Yaakov didn’t want to say Sheker (to say he was Eisav). Although in the end he did say Sheker, he still remains the prime example of a man of truth.
We see that not only is: אוֹנ סַר ח מָ נָאַַ פ ט ר יהַַב"קַכחַב (you are not punished for something is beyond your control), but those who didn’t want to do evil can be considered special in the same area they were Nichshal! We can suggest that although Shaul was loaded with Kin'ah against Dovid, he is probably totally innocent because he had a Ruach Ra’ah. And he surely wished to be a total Ayin Tova person, since Dovid who symbolizes Malchus was unusual in Ayin Tova.
