Kufr

Q: My question is if a Muslim watches fictious super hero movies like spiderman and other super hero movies in which they show a super hero getting alive again after death. The superhero that is considered god of thunder, and other fictious movies which show devils, evil spirits (horror) etc. in. Does watching all these superhero movies nullify a person from Islam? I know watching movies is not permissible but I want to know does this nullify Islam? Because lot of children and adult Muslims watch super hero and horror movies of these types and enjoy.

Q: I played very good football. My friend told me "nice Ronaldo". I smiled at him, thinking and accepting that I am Ronaldo and becoming happy about it. Ronaldo is a Christian footballer. Did I commit kufr by thinking and becoming happy that someone called me a Christian (by calling me Ronaldo)?

Q:

1. If someone does kufr (by mocking islam) after that he comes to know its kufr, is it necessary to say shahadah and repent?

Case1: I am asking this because if a person doesn't know its sin, he won't be getting any sin right? Then why is shahadah and repentance required (if he is not gettig sin).

2. If I said to someone that "making fun of islam is kufr and whoever does this is, is a kafir and needs to repent and say shahdah again to become muslim." Instead of knowing the correct ruling, i just purposely told him to do repentance and say shahadah again to become muslim. Did i commit kufr by making halal haram by telling someone to do an act which is not required and telling them only if u do this then you become muslim. 

Q: If a Muslim has a doubt concerning an Islamic thing, like he heard someone say something about Islam but its widely accepted thing and he gets doubt that if its true or not. If true where is the proof? Like these thoughts. Now I he gets free time and wastes it. Will he be regarded as a kaafir?

Q: If a non muslim is made known about islam and he is in doubt about his religeon. If he spends free time on useless things and doesn't search about Islam and dies. Will he be regarded as a kafir?

Q: This question is very important. In fact, almost all committing this sin face this, but do not think about it and do not ask about it. Will this be a kufr to watch pornography and masturbate, in which actors pronounce the name of God during adultery and/or they utter phrases that offend God, during adultery? Will this be contentment with unbelief and with an insult to God, if muslim does not agree with these words and actions in the heart?

Q: A friend of mine said to me that Allah is testing me in the worst way possible. Is it kufr?

Q: My sister is currently set to graduate at the end of this year, after which she will join the rest of my family in Turkey. However, this term she took a biology course that had multiple chapters regarding human evolution. She is now preparing for the exam for that course, and the chapters on human evolution happen to be a large part of the exam. If she doesn't answer the questions, she will most likely fail and if not, her average would become very low, and it may effect her graduation or her ability to move to Turkey at the end of the year. Can she write a general statement like 'so and so theorized this' without any indication of agreement and without stating anything as a fact? If not, is there any way for her to answer the questions (in written form) related to human evolution without falling into kufr?

Also, from what I know, medical schools even in Islamic Countries rely on biology books that include topics like human evolution, and the students are tested on the theories. How can Muslim students graduate as doctors without getting near kufr?

Q: Suppose that I was explaining a question of maths to another person. He was weak in maths so he could not understand properly what I explained. Then I mocked at him that you couldn't understand this simple problem and others also laughed at him. Then, because I mocked at someone who was trying to learn something. Learning to score good marks and please his parents. Pleasing his parents to please Allah. So indirectly I mocked at him while he was trying to please Allah. Is this kufr indirectly? Mocking on a person who tried to please Allah.

Q: Someone sent me a page telling about the weirdest shows, the description of the show read that: 'A 2009 Turkish reality show where an imam, a Greek Orthodox priest, a Buddhist monk and a rabbi compete to convert atheists to their respective religion. Anyone who was persuaded to change their religion won a pilgrimage to the spiritual home of their new belief system – so a bit like Take Me Out but with less Fernando's and more, you know, Mecca.' Is this description blasphemous? Please tell me so I may report it to cyber crime authorities thank you.
