Does watching pornography and being exposed to provocative images on social media brand a person as corrupt and disobedient, and what are the ways to distance oneself from such practices?

To abandon pornography, you need strong will and firm determination after seeking Allah's help, and you must avoid everything that incites desire for it, such as images on social media. What strengthens one's will is being mindful of Allah's watchful eye and fearing a bad end. The hardship of striving is strong at the beginning, but it eases with persistence. If news websites and social media lead you to relapse, then refrain from them to safeguard your religion. As for destiny (qadar), it is Allah's secret, and it is not permissible to use it as an excuse to commit sins; rather, the duty is to adhere to Allah's law.
