Pity, Sympathy, Mercy, Compassion
noun
You have your feelings... these are the feelings humans have. When you ask someone to have feelings (Have feelings, KAY?? (け at the end)), you are asking them to pity or have mercy on you. Please! Have those human feelings that people have, like sympathy or pity. Don't kill me, man!
なさけ
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: Who are you begging to have pity on you? It's NASA. They have you hanging outside of the space station and they're going to push you towards earth where you'll burn up in the atmosphere. You don't want that, so you beg mission control for some pity. What will they do? You decide.
アイツは情けのカケラもない男だよ。

お前に情けをかけられるなんて、ホント情けないよ。
It's truly pathetic that I have to receive mercy from you.
