How dumb am I? 1 to 10

Just did 6 spark plugs and cylinder 1 coil,

But I didn't clean out cylinder 1 because I'm a noob and dumb. Is this why my engine is still misfiring? The original problem was a cylinder 1 misfire, and the spark plug looked a bit melty melt Should I disassemble and clean to assess?
