"kindliness" - Translation from English to Arabic

I aim to prove that kindliness and pitilessness go together.
أريد أن أثبت أن الطيبة والقسوة قد يجتمعا.

The old minister spent most of his life here... quietly building up his parish... sharing the simple life of his neighborhood... and, somehow, imbuing his parishioners... with some of his own kindliness and humanity.
الكاهن المسن قضى معظم حياته هنا بهدوء يبني ابرشيته يشارك الحياة البسيطة لجيرانه

kindliness and sincerity... and, if you'll forgive me, modesty... mean more to a husband than all the wit and beauty in the world.
العطف والإخلاص ..... وإذا سمحتِ لى , التواضع

I wanted to show by my marriage that though he was led astray, as I believe by that innate kindliness and courtesy of his which made it so hard for him to rebuff the advances of a woman,
... أردتُ أن أظهر من خلال زواجـي ... الاعتقاد بأنه قد ضل ، حسبما أؤمن ... بطيبته و احترامه الفطريّ

This goes against the rich tradition of Islam, as articulated by Imam Ali ibn Abi Talib, peace be upon him, who says in an instruction to his new governor in Egypt, Malik al-Ashtar: " Develop in your heart the feeling of love for your people and let it be the source of kindliness and blessing to them.
وهذا يتعارض مع تقاليد الإسلام السمحة كما عبر عنها الإمام على بن أبي طالب رضي الله عنه عندما قال في تعليماته إلى واليه الجديد في مصر مال الأشتر: " ازرع في قلبك شعور المحبـــة لشعبك وليكن ذلك مصدر رحمة بهم وبركة عليهم.
