What kind of genetic engineering would be required to give a human-animal hybrid the following characteristics?

In my world, taking place sometime in the near future, scientists decide to mess around with genetic engineering. The goal is to create hybrid supersoldiers with animal genes ad have them perform espionage/assassination missions on high-ranking targets. But research goes wrong and the hybrids end up with some features that the researchers didn't intend for.

The hybrids should end up having the following characteristics:

• Enhanced strength and speed (but not overly so - they will be stronger and faster than the average human but super powered or anything)
• Avoidance of sunlight and bright lights, and more active during the night. Maybe they could be weak to fire
• They have cannibalistic tendencies and specifically target humans as their food source
• They are the carrier of an unknown but deadly virus that very few normal humans are immune to
• Poor vision but very strong smell and hearing

What kind gene engineering, or rather, errors in the engineering, would be required to produce such a hybrid? Essentially, a lot of these features, such as avoidance of light and bad vision, are not exactly conducive to being good covert soldiers, so there would need to be some human error to produce these results I'm guessing
