People who make decisions based on emotion and justify those decisions with logic afterwards are poor decision makers.

I completely agree with the statement that people who make decisions based on emotion and proceed to justify their decisions with logic afterwards are poor decision makers. I believe it is so because of two reasons, on which I shall further elaborate.

Firstly, I believe decision-making, to the greatest possible extent, should be a process based upon logic and not based upon emotion. Granted, there are situations in which there is few information available, but that does not justify any emotional decisions. One could imagine, for example, what would have happened to World War II Japan if emperor Hirohito, after the atomic bombings of Hiroshima and Nagasaki, would make the emotional decision to keep fighting the US forces in his territory: rather than the hundreds of thousand dead, most probably millions of his people would have perished. Thankfully, the emperor decided to sign the unconditional surrender of his country, thus ending World War II and sparing scores of lives.

Second, in the event that some emotional decision turns out to be correct, there may always be a probability that a stroke of luck might have turned events favorable and a potentially poor, unthought decision, to a happy ending. Taking adavantage of the erstwhile example, if the Japanese emperor would have chosen to fight to the bitter end, influenced by the opinion of his advisors and his own people, and for some reason his country would have been victorious (despite the huge odds against such victory), the leader could not affirm his decision was logic, given how unlikely a victorious campaign would be.

To put it briefly, I believe people who make decisions based upon emotions rather than logic, and use logic itself to justify their decisions are poor decision makers because emotional decisions may have potentially devastating, undefensable consequences. In addition, an emotional decision that turns out to be a correct one may be so because of chance or luck. Decison making should always be a rational process, no matter how small the amount of information one has to make a decision.
