In regards to acid rain, I understand that all rain is acidic, but that "acid rain" is more harmful. Is that because it is more concentrated in terms of morality or because it more acidic?

One of the ways acid rain is harmful is due to its higher acidity. Its lower pH values would greatly harm the pH levels of marine life as well as terrestrial soil, causing lots of damage.

Acid rain is more acidic in terms of molality (you spelled it morality, which is indeed a quite different term), but it is also harmful because a sudden increase in acidity, even in small amounts, can disrupt the equilibrium, which is harmful to wildlife.

Acid rain is bad for the environment because it changes the pH of a lot of things that depend on a certain pH level. For instance, plants prefer soil at a certain pH and acid rain disrupts this pH. This means the plants' enzymes will not be at a preferred environment, leading to less activity or denaturation.

All rain is acidic because CO2 in air will be dissolved and form carbonic acid; however, acid rain are formed by SO2 dissolved in water and forming sulfuric acid which is a strong acid and more harmful.

Acid rain often forms from the reaction between CO2 and H2O. The resulting product is H2CO3, which is carbonic acid.
