No. Walker may be pretty bad, and his plan of freezing the world over no doubt would've caused mass death and destruction, but in the grand scheme of the DCAU he barely sticks out from all the other villains who have had similar plots to take over the Earth. Hell, Ra's al Ghul tried to perform a similar scheme about a season or two before he was ever introduced (only he wanted to destroy humanity by overflowing the Lazarus Pits) and in that case it was made way more clear how destructive his plan was; with him stating the actual, calculated number of people that would be killed (two billion, fifty-six million, nine-hundred eighty-six thousand, to be exact). And all he does beyond that is try to kill Batman, Robin and Freeze, which is standard villainy at it's finest.
