I want to install a kitchen range hood. I don't know if I should vent it out the side or up through the attic to outside?

The range hood will be installed against an outside wall so side venting only requires one quick 4" core taken out of the brick siding.

But is it a bad idea?

If it's a single story, and the exhaust air is gonna get trapped under the soffit, or sucked into the soffit vents, I'd go thru the roof. If there's another story above, so the soffit is 8 feet up and routing to the roof is difficult, I'd go out the side.
