It is curious that our own offenses should seem so much less heinous than the offenses of others.

【翻译】奇怪的是，我们自己的过错远不如别人的过错可恶。（自己的过错比别人的过错更容易原谅。）

【分析】

1. It is curious that ...should...是一个虚拟语气句。

2. 比较级形式：so much less heinous than... 远比......不可耻。

3. the offenses of others 意思等于：the ones of others 或those of others，但考虑到ones, those, others都是代词，避免在一起混用。为了突出名词offenses，故为之。尤其建议尽量不要说the ones of others。
