Mutations are harmful if they decrease the function of some part of the body. Unfortunately, this is the case far more often than them making an improvement.
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
A silent mutation is less harmful to an organism because it does not change the amino acid sequence of the resulting protein. This means that the protein's function is not altered by the mutation, minimizing its impact on the organism's health and survival.
A mutation is considered beneficial if it confers a selective advantage that improves the organism's chances of survival and reproduction in its environment. Harmful mutations typically decrease an organism's fitness and can be detrimental to its survival. The impact of a mutation on an organism's survival depends on the specific environment and circumstances in which it finds itself.
If a mutation happens, it will be helpful, harmful or neutral. Whether they are passed on to offspring depends on several things.Obviously, whether the organism gets a chance to reproduce.Whether the organism manages to survive long enough to reproduce, which it is unlikely to do if the mutation is harmful.Whether the gametes which are successful in the process of fertilization happen to contain that gene.

environment and the specific role of the gene that is mutated. In some cases, a mutation may provide an advantage, allowing an organism to better survive and reproduce. In other cases, a mutation may be harmful if it disrupts essential functions or causes diseases.
Because the chemicals inside the beneficial burn away the organism.
a mutation is sometimes a form of adaptation, but if something changes in the DNA of the species and could possibly be harmful to it, that is a harmful mutation.Examples:-born without a part of the brain-cancer is a form of a harmful mutation-hypoglycemia
Not all mutations are harmful. A mutation the give the organism antibiotic resistance, for example, is quite helpful. A different mutation that causes a necessary protein to misfold may result in death. In general mutations that affect proteins that are necessary for life will result in the death of the organism. One such mutation is in the protein p53 which is necessary to prevent a cell from growing uncontrollable (cancer). A mutation in p53 could result in a cell with damaged DNA to reproduce - this is what we call cancer.
A change in the DNA of an organism is known as a mutation. Mutations can occur due to errors during DNA replication, exposure to mutagens, or genetic recombination. These changes can lead to variations in traits, which may be beneficial, harmful, or neutral to the organism.

Mutation can be caused by many factors (birth defects, exposure, etc.). It is often times harmful (in birth defects: person with three #23 chromosomes; in exposure: a person handling uranium). (sometimes exposure can often kill off cancer [but then again so can Chemo])
