 You can remove the method only in the class where this method is defined
 (in Foo in your case)

D> class Bar < Foo
D>    remove_method(:val1)

 Is this was valid then you'll have problem with

class Foo
   attr_reader :val1, :val2
   def initialize
      @val1 = "hello"
      @val2 = "world"
   end
end

class A < Foo
end

class Bar < Foo
   remove_method(:val1)
end

 #val1 will also be removed for A
 
 Use undef_method if you want just to modify Bar
