Just like goodness has many levels to the point that Abu bakr has more iman than the rest of ummah. Evil too has many levels. The level of kufr of an ordinary infidel is not the same as the level of kufr of the pharaoh. The level of kufr of the pharaoh is not the same as the level of kufr of the dajjal. The level of kufr of the dajjal is not the same as the level of kufr of majooj yajool. The level of kufr of majooj yajool is not the same as the level of kufr of iblis. My question is: In the infinite world of sins that are so complicated because if someone for example lies and his lie causes two murders he has also the sins of murder and all the bad consequences. The sins of the heart that caused iblis to reach that level. My question is: Can ordinary sins like adultery, watching pornography, bad behavior lead to much bigger sins like kufr and even to the level of kufr of dajjal? The dajjal in the beginning has been an ordinary human being like me and you in the first years of his life when he was a small child. The same regarding the pharaoh, majooj yajool, and iblis. Certainly they didn't begin with the biggest sins. Certainly they begun with smaller sins like adultery, backbiting and ended up with the biggest level of kufr that distinguishes them from all other creatures and made them so famous in all those narrations in the quran and Hadith. I am making this question because I like watching beautiful women in the internet with the idea that this will never lead to something much bigger like kufr, shirk or big sins of the heart and illnesses of the heart that caused iblis, majooj yajool and the dajjal to reach that level of kufr and sinfulness. I do this with the idea that this sins will never lead to bigger sins like kufr or minor shirk. Please advise me on this issue. Please give a long and detailed answer.
