Selling Alcohol
What do you mean by “no other way” ? Do you mean there is no other job available only then selling alcohol is permitted? By that logic, working in bank is also the same.
Being forced is being forced
Victim of murder is not helping the murderer, in fact he opposes the murderer and fails to do so . A bank for example is helping the account holder to earn interest. Bank is not a victim or forced to pay interest.
