Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
It is only possible to know the impact that Lasher had on Walter's life if you read the text. However, you can consider that this impact was transfomative, if Lasher was able to modify Walter's life in an intense and powerful way. You can consider that this impact was traumatic, if Lasher only promoted disgust and bad experiences for Walter. You can consider that this impact was ordinary, if Lasher did not promote anything intense in Walter's life, without provoking any remarkable and transforming experience. Finally, you can consider that this impact was ambiguous, if at the same time that Lasher promoted good things in Walter's life, he also promoted bad things, making it impossible to determine whether Lasher's presence was positive or negative.
