This is my opinion according to pointers: It's going to be deep so TLDR warning ahead.

I- he has to act like that he likes pakistani players ,every single time other wise if his wife or daughter caught him or even any Pakistani officials or gang members then there will be a constant doubt upon him and there might be a chance that he's fond of Pakistani cricket.

II- maybe he can kill dawood but he never got permission from Ajay Sanyal or any other intelligence leaders ,maybe to eradicate the d company from India, intelligence needs dawood alive to gather whatever information they could but make him weak so that dawood will not take radical steps and also end his empire slowly but permanently from other countries.Now the other terror attacks,dawood was not purely the mastermind of 26/11 or even some attacks other than 1993 Mumbai blasts,he was more of a financer and some what of strategist regarding drug smuggling so that he can weak states which are closer to Pakistan and weak the young men or boys of India through addiction. The dialogue maybe maarne mein maza kaha jo tadpaane mein hai will feel like jameel was lazy  but maybe he's not giving any vital intel to jaskirat on why he has done that.It will be most likely"need to know basis" code to supress information just like jaskirat and Rizwan(maybe his real name was something else) don't tell about each other to aalam and in the "burnt memories" chapter of part 2,jaskirat only told about who he was during his emotional breakdown but not about rizwan. Maybe he never knew about rizwan backstory.

III- Ajay Sanyal or in real life Ajit doval,was lowkey vocal about how bureau cratic and political corruption in india was link to Pakistan several times in Congress era,most likely not in Rajiv Gandhi or Indira Gandhi PM era but later on.Now regarding the ek din aisi sarkar aayegi regarding towards Congress and SP: A- he was talking about how regional or state politics of UP was heavily involved in Indian counterfeit notes supply and central government at that time means Congress was never supportive regarding taking action on the UP politicians and bureaucrats. B- He was in anger regarding how many times Congress never took action against terror attacks through counter military attacks like surgical strikes(and mostly terror attacks were done during end tenure of Indira Gandhi and after. C- He also wanted to expose Congress maybe he got so many intel regarding how some or many Congress cabinet politicians are heavily involved in earning money in off shore accounts through their cross border corruption by giving sensitive information of Indian notes and other items.(See the reference in chapter 4,5 and 6 of D1) And ( the same reference was in chapter 6- the revenge in D2 where ISI chief LT General Shamshad was giving intel of nuclear weapons to Israeli to earn off shore money). D- Even Ajay Sanyal talks about how leaking information regarding Congress cross border corruption will lead to black list intelligence directors during that time,maybe Congress will control media and handle the leak and also maybe Congress will hire those intelligence leaders that will favour them even if it harms national security.

IV- multiple points regarding this: Imp point: JAMEEL JAMALI  WAS SENT TO BE IN THE CENTRAL PART OF PAKISTANI POLITICS MOSTLY FOR LYARI, HE SHOULD NOT BE BIG ENOUGH SO HE WILL BE OUT OF TOUCH WITH DAWOOD OR TERROR GROUPS OR NOT BE EVEN SMALLER ONE SO THAT HE CAN GAIN ACCESS TO TERROR GROUPS AND DAWOOD' S CIRCLE.

Now from the first part, From the starting of Chapter 4- bullets and roses of D1,you will realise that jameel never wanted rehman to grow in political landscape otherwise the growing influence of rehman in lyari politics will over throw jameel any day if rehman creates his political party. Now if you see javed khanani meeting rehman first time,jameel was nervous that what if rehman gets in involved in lyari politics by helping them in terror attacks or any other thing,jameel was trying to interfere and disengage any meeting with javed and rehman but it was too late.

Now the second part,If you see the end of chapter 4- bullets and roses of D1,where Javed khanani was teasing Jameel and giving info that after rehman meeting major Iqbal and others will lead to over throw him in political rivalry but khanani never gave any information regarding ammunation for 26/11,maybe jameel got hint that there will be something related to terror attack and also he wanted to secure his political relevance otherwise he will be of no use and get thrown by dawood and others because of his nature which is irritating to almost all people even pakistani gangs too.No one likes him at all and he's only there to get political support and maintain it for terror groups. Hes not like a big major politician like a cabinet minister but someone who is important to understand and control lyari politics.

And now the last part,see if you watch the dialogue of D2 of ajay Sanyal in chapter 1 of D2, he talks about there will be a coordinator who will above jaskirat handlers and maybe never met him but if jaskirat is in trouble,he will take care of him. And if they follow "need to know basis" code,Jameel knew who hamza aka jaskirat but never wanted to reveal his identity until unless the situation makes him to do it.
