If your making a tough decision, you have already determined that both options are equally attractive and equally good decisions. If this wasn't the case, it would be an easy choice. So if you are choosing between two seemingly equally good decisions, your choice doesn't matter. They are both equally good options, and so are the same level of risk in having a bad outcome.
What we usually think of as "tough decision" is that there is an easy and attractive choice vs. a choice that requires sacrifice without immediate benefits. Or it puts conflicting choices in opposition with each other. Typically in that one, the decider has a conflict of interest. E.g. mask mandates in a covid-stricken region probably save a lot of lives and are probably supported by a majority, but get the politician thrown out of office by an angry minority of anti-maskers. So the politician has to weigh staying in office against public health.
In your example there is one clearly right decision and one clearly wrong decision. It's not a difficult decision, it's a moral one (right vs wrong), which isn't a difficult decision at all. Just because thr outcome may be difficult for the decider doesn't mean the decision itself is difficult.
