Becoming a data analyst

Q: I want to become a data analyst, I am choosing a field, I have cherry picked the top most valuable & highest paying field they are:

1. Finance & Banking
2. IT Companies:
3. Pharmaceuticals and Life Sciences

Now I wanna choose a highest rewarding field too.

My question: "Narrated by Ibn 'Abbas (radhiyallahu anhuma): The Prophet (sallallahu alaihi wasallam) cursed the one who consumes riba (usury or interest), the one who gives it, the one who records it, and the two witnesses to the transaction, and he said, 'They are all alike (in sin).'" (Sahih al-Bukhari)

Now if I become a financial data analyst, most probably I may have to record about any such possible riba transactions taken or given by company/banks etc.. Wont I be the sinner

2. Because of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely. And whoever saves one - it is as if he had saved mankind entirely. does it applicable to my role as Pharmaceuticals and Life Sciences data analyst. it may also explore my way to have a Islamic finance field innovation.

3. Data analyst in IT companies play a significant role in developing technology and improving business operations, also it lead to me to gain more salary making me to give charity & other acts.

I would like to have your opinion on the best job role which you think will be with your islamic knowledge.

Selling cigarettes

Q: I live with my grandparents and they have a shop which sell mostly biscuits & they also sell cigarattes! (According to some sholars in my country cigrattes are makrooh, while I have heard some Arab scholars say its haraam).

I want to be on the safe side so, as I live in their house my concern is I use electricity/internet to learn as I learn online! Will my online earning be halal if I pay them later on for electricity/internet I use?
