I think its a good effort. You may add one more practical example to justify your point. I have underlined/edited some words to suggest some corrections. You should also take due care of punctuation.

Eventually all Human Action must be judged by its moral contents
Human actions are the main identity of human conduct. The world is abound with many vices and due to the materialistic approach of the people, human actions are mostly in conformity with customs of the society. These customs are the approved standards of morality enacted for the self-interest, therefore, their violation brings animadversion of the whole society. Morality is considered as a code or principle deals(dealing) with right and wrong or good and bad behavior. Therefore, it is always argued that all human actions must be judged by its moral contents rather than customs prevalent in the society.
In a(the) world in general and Pakistan in particular(,) human actions are inclined towards customs prevalent in the society. Whenever, a renowned personality or a person affiliated with a political/religious organization is killed, the violence erupts which leads to the loss of several lives and property. It is due to the leaning of people towards customary morality rather than to act deliberately by keeping in view the moral values and responsibility.
Hazart Muhammad (PBUH) lived an exemplary life and the whole life was comprised of love and obedience, complete trust and thoughtfulness, peace and appreciation. In his whole life, whatever, he seemed wrong he openly denounced and forbade people,(.) h(H)owever, he always enjoined people to adopt altruistic approach. His behavior with the people raised him to the exalted position among people and not only friend but also foes praised for his conduct. Resultantly, due to his noble behavior, Islam flourished by leaps and bound as actions(action) speaks louder than words.
The world is replete with many vices and due to materialistic approach;(,) the societies have developed customary morality in order to safeguard their interest(s). Therefore, there is no denying fact that all human action must be judged by its moral contents.
