Found this sentence:
両親が死んだというのに、悲しもうとすらしない俺に向けられる目が。クズみたいなニートに向けられる目、敵意。軽蔑。
That に in 「悲しもうとすらしない俺に向けられる目が」is acting as the indirect object or is it marking the doer? Since it's a passive sentence.
This ~に is marking the target/destination of the 目. ~に used in a passive construction does not necessarily mark the doer (agent).
俺に向けられる目
stares cast to me
(not "stares cast by me")
