Good whisky "opens" with just a few drops of water added. It does not ruin it... adding several ice cubes on the other hand only makes it easier to drink by those that do not like whiskey.
One cold rainy night in Scotland I stopped at a rural inn to enjoy the open fire and a wee dram. My straight Laphroaig came with a tiny pitcher of water so I could add a few drops or as much as suited me.
